MIT grad shows how to simplify radical expressions, specifically square root expressions, into their simplest form ("Simplified Radical Form" or "SRF Form"). To skip ahead: 1) for a PERFECT SQUARE under the root like sqrt(16) skip to time 1:29. 2) for a SMALL number under the root that is NOT a perfect square like sqrt(32), skip to time 2:45. 3) for a LARGE number under the root, such as sqrt(343), skip to 5:14. 4) for a PRODUCT, meaning a number times a square root like 5*sqrt(54) skip to 7:30. 5) for a QUOTIENT, meaning a number divided by a square root like 4/sqrt(2), and where you have to RATIONALIZE the denominator, skip to 10:10. and 6) for a more complex QUOTIENT example like (4+sqrt(3))/(5-sqrt(3)) where you have to multiply by the CONJUGATE to simplify, skip to 12:36. Nancy formerly of MathBFF explains the steps.

For all simplifying radical problems:
1) First try to find a perfect square number that divides evenly into the number under the square root. Perfect square numbers include 4, 9, 16, 25, 36, 49, etc. because they are squares of the numbers 2, 3, 4, 5, 6, 7, etc., respectively.
2) Separate the root expression into the two numbers you found as factors, with each number now under its own square root symbol. For example, sqrt(12) = sqrt(4) times sqrt(3).
3) Keep simplifying. The square root of a perfect square becomes just a number, without the radical square root symbol. sqrt(4)*sqrt(3) becomes 2*sqrt(3).
4) Check to see if anymore simplifying can be done, either by combining constants or finding another perfect square number that divides evenly into your factors. If no more simplifying can be done, you have your final "simplified radical form" (SRF) answer, 2*sqrt(3).
If there is a square root anywhere in the DENOMINATOR, you must "rationalize" the denominator, in other words, somehow get rid of the root in the bottom, in order for the expression to be considered simplest. For example, if you have 4/sqrt(2) you must use the trick of simplifying by multiplying the expression by sqrt(2)/sqrt(2). This will clear the square root in the bottom. If you multiply straight across, you would get 4*sqrt(2)/2, which simplifies again to 2*sqrt(2).
If you have a more complicated fraction with a square root in the denominator, like (4+sqrt(3))/(5-sqrt(3)), you will need to use the "conjugate" to simplify. This means multiplying top and bottom by the expression in the denominator, but with the middle sign flipped. Here you would multiply by (5+sqrt(3))/(5+sqrt(3)), multiply straight across on top and bottom using FOIL-ing and distribution. Some terms will cancel in the bottom, leaving you with a simpler denominator that has no square roots.

You’re the best! 😊
in the U.K. we call them surds
It was just a joke. By absolute I mean the absolute value of a number such as 2 or -2. |-2| = 2.
Robbae in here we call them turds
@Milbox R 😂😂😂😂😂
In America, we call you a turd.
@RobbaeAbsolute is the value of the distance from 0.
Make a video for functions pls
(a+b)(a–b) = a^2 – b^2
please do videos on iequalities!!!
nancy for president
D3lete more like Obama for President again
Orange man bad!
I lve u
I love you ❤💜
i want to be friend with her
You make mathematics interesting .
very attractive, very nice, very smart thumbs up
Jeff M Y’all act like you’re reviewing a car or some shit. “Very nice”
@Irene M hahaaaaa
What if the sqrt of 121 was raised by a cube?
“It’s okay you don’t have to like math but you can like my videos”
@Franck’s Notes She doesn’t speak French, does she?
VanClaaude She might 🤷🏾♂️
@Franck’s Notes She could be a Wookie for what I care, she’d still be cute.
@Proman974 -BGS what else is he supposed to like her for? Her personality? Shes teaching math lmao tf wrong with u
Its ok mam
Nancy, level with us. What planet were you and Einstein, Planck, and Descartes really born on?
thank you. i understand so much more now
I dont understand
Can I say if there is under root square is cubed are number root the number?
Let n=x^3 if( x^3 )^1÷2 = x . (X^1÷2) is that true ??
Thx 4 all ur help
This 17 minute duration video helps me alot than a 1 hour lecture of this lesson
Thank you for the help.
These videos cover a year’s work
@Leonhard Euler trueee trueee
I AM LITERALLY CRYING. I am SAYING bro some Teachers should JUST not TEACH and Assignment Homework videos (WIth NancyPi as a Guide!) For REAL For REAL!
Daniel Jon facts
can she write backwards or something??
Or she on the otherside
Flipping image in editing won’t work. I think this is how she does it. And the only way I can think of that can create this kind of effect. Here’s a pic to illustrate my point.
she reverses it just like your t shirt in a selfie cam or mirror does
I am also very confusion about that
Nancy is a god
Thanx mam here it is known as surds.
mam you mathed is so very well..
Nancy, you look like my ex gf…. at least you gave me something that makes sense. Saved my grade tonight; high five! (I forgot all of this high school math about ten years ago)
We can simplify denominator
We know that the vale by the learning of Exponent √=1/2
Then we can use it
We can simplify denominator
4√2/2½+2½ ( we add the power not add base if u can understand)
Another method to solve it
4+√3 * 5+√3/5-√3*5+√3
In numerator only use distributive law of algebra
So we get
23+9√3/ 5-√3*5+√3 ( in denominator we can use algebra identities we can use (x+y) (X- y) = x²-y²
So we get
Thanks, Nancy, you explain math so clearly. God bless you, Nancy.
What is her writing backwards huh
mam you are very beutyfull your voice is magical l like you
Ty for this video my math teacher is garb
I don’t know why but as a portuguese speaker (I live in Brazil) it’s easier for me to watch an english lesson rather then a portuguese lesson. Is this strange?
@Fuinha Amiguinha kkkkj
your appearance is a little stranger
@Archer I am also Brazilian but I don´t think it has anything to do with that. It really comes down to the teacher. She speaks in a calm manner, not in a condescending tone and take her time. A Brazilian teacher would speak really fast as if you were suppose to follow and keep up with him or her in every step of the way. At least all the ones I had were like that.
are you sure the reason is the language ? shouldn’t it be the girl ?
@Camembert d’Alembert yeeeeeeeeeeeeeeees thank you for pointing that out!
Nancy, your video was very helpful. I never understood how to simplify radicals. Watching your video has given me a better understanding. Thank you for sharing.
This is legit the most helpful vid on the internet
It’s not a shortest way you should apply formula to solve it easily
Nancy can you make videos that can help people taking the SAT or the ACT
@Maddie Patty thank you 😊
@Charlie Kowtarapu did you get into the college you wanted?
Maddie Patty I took it in 8th grade so IDK yet. But you’ll be fine as long as you study a decent amount. It isn’t super difficult
@Charlie Kowtarapu im going into 9th after the summer – how was it?
Maddie Patty it was pretty simple and not super hard
square root of 125 is not equal to 15 square root of 6. It should be 5 square root of 5.
Walid Abdulrahim why is that?
*does default dance*
Jake Truell pew new new new new *claps*
B3 MY T34CH3R PLZZZZZZZ
Thank u I have a test tomorrow and u helped a lot !!!
thank you so much Ms. Nancy you make Math easy to me.
Amazing video helped me a lot thank you😊
thanks this really helped both me and my seven year old.😊
This will up him to the next level and he won’t tell me he’s bored.☺
Excellent,but what the use of learning these.
Thank you so much!!!! I watched 2 videos b4 yours and was still lost. You explained it wonderfully and now I finally get it!
YOU EDUCATED ME! 😃😃😃
nancy is hot
Thank for explaining it easier
this is sooo helpful !
My teacher taking an hour and this woman explaining more in depth than my teacher in just 17 minutes
this is so helpful🙏🏼🙏🏼🙏🏼
OMG thank you for saving me from a night of weeping over my trig homework, because it’s been a hot minute since I worked with radicals.
A beauty gifted with knowledge
Gifted? Lol She practiced. A lot.
Your so beautiful i wish to will date us
You taught me more than my instructor could in 1hr and15 minutes!! Thank You So Much!! I LOve your name by the way!!lol
I JUST WANNA TAKE THE TIME OUT TO THANK YOU ❤️❤️
I really love your videos. But can you make a video on some topic that wrecks our brain, that makes us push harder, a videos for pro mathematicians.
Here’s a great problem for you:
Let p be a prime. Find all solutions in positive integers of the equation(2/a)+(3/b)=(5/p).
*I solved this question using modular arithmetic. Do you have some better solution?
What would this be used for? Is there a practical application?
9:08 couldn’t you simplify the square root of 6 into square of 2 times square root of 3? That’s what we did to 54 so why would we not apply the same rule to the 6? Or is it because it’s not one of those perfect square numbers?
Amazing teacher🙏🏼thank you sm
Very helpful! In calculus these radicals get more complicated, and its easy to forget the simple rules!
I’m just impressed to the fact that you’re able to write backwards. If I tried to write 1+ 1= 2 backwards I think would experience a stroke.
Vic Sehmbi lmao
She’s sexy and she knows it
You deserve more subscribers!
How am I supposed to concentrate when you look like that?
Hard to focus on lesson with her face.
Is this is difficult ?? In India we learn all this in middle school
Anmol Jyoti the problem is u never use this in the real world so your brain classifies it as useless and its forgotten. It’s a waste of time learning something like this in the first place in my opinion unless you’re pursuing accounting or physics maybe.
I was trying to find the sqrt of 180 and started with 2 times 90 and the answer was 6 sqrt15 but when I checked to see if my answer is correct the answer was 6 sqrt5. Can you tell me where I was wrong and why please?
James Hetfield, you are so wrong. The answer is 5 sqrt 6. The highest square that goes in to 180 is 36. 36 squared is 6. 36 times 5 is 180. Therefore the answer is 5 square root 6.(I’m nine and one half.)
James Hetfield , wait you are right. Sorry.
I have a lot of problems with this in school
Please make video on surface areas and volume
Who is Ur teacher
Very helpful, thank you
cool, but give Russian subtitles please
Let’s hear it for the lefty’s!!
I never knew that learning math could be so sexy.
Thank you so much sweetie! Your videos helped me a lot in math class! 😘😘
i like math now
Thanks a lot Ms. Nancy. I understand it much better. God Bless! 🙂
thank you so much! This solved my one week long problems.
Thank you, Nancy, Your delivery is awesome.
With you, math is super fun. Like a game.
Algebra sucks ass but you’re cute lol
thank you 💓
I can’t pay attention
That cute soft speaking is not working! This is math, you MUST speak up in order for students to understand. I had a math teacher in college and she used local Chicago gangs as certain calculations. She lost me right there, and I had to take the dam class again and it dropped my GPA!
kel2580 But… this is a YouTube video, not school. Obviously the people watching it aren’t being forced to watch it and are watching to help themselves outside of school so they are going to listen, or else they wouldn’t be watching.
I don’t get it!
Just realized she’s writing backwards
Only video that helped lol
be my wife nancy
12:00 square 2 times square 2 is 4 then the square of 4 is 2 . is that applicable to other problems .
Thank you so much for sharing and I think you a pit hot to be teacher .
Don’t you work less if you use the greatest perfect square instead of working from the “4” up? For example, 16 is the greatest perfect square of 32, and 16 has a perfect square of 4, giving you 4 root 2, in two simple steps.
She’s an angel
I wish I could keep watching your mathematic lessons because I believe I can improve thanks alot you’re just magicians:)
Missed one day of school, came back completely lost when I came back and the teacher gave me hw on this. Thank you so much, great video, makes perfect sense.
this motivates me to learn math
Thanks fam, I owe you a sandwich
Thank you so much. It was really helpful.😊😊
Uh…how can i add unlike squareroots ..which cannot be simplified?
Very helpful video! She explains each step very clearly…thank you!
@9:34 it helps me so much !!!!, thank you so much
It helped me a lot!!😅😅💕💕💕💕💖
Thank you so much,
Wish that more videos to come!🙏🙏🙏😅😅💖💖💕😆
Heyy Nancy😅😅Can you make a video that will encourage us TO LOVE MATHEMATICS😅😅😅😅🙏🙏💖💖
This girl is magical
are she single? just asking
Aside from being absolutely stunning….is anybody’s mind blown that this chick is writing left handed AND backwards? WOW!
im not gonna lie its really hard for me to concentrate when she looks like that so pretty,smart and sexy thats what i like the most on girls,,,,,,,if shen gonna be my teacher i will never be absent on class
She’s so hot & that makes it so much easier to learn cuz im glued to the screen
got a question how can you simplify this radical expression (2sqrt(6))(5sqrt(10))
Nancy, i love your knowledge! you teach me how to solve roots with perfect sq. and not perfect sq.
What’s the little transition noise?
Thought the same thing.
Thank you for the help.
My math teacher explained much differently making it harder for me to understand
I don’t know any of this stuff, but is kind easy to grabbed. As long as you know about that list of perfect squares, is all you need. Thanks Nancy, again.
I love you pie. explanation
Thank you Nancy! You have refreshed my math memory on the conjugates.
Also, wow… Try quenching your thirst by drinking some H2O boys !!!
I have a teacher that couldn’t teach for their life. You just helped me out because I was almost on the verge of crying my eyes out. Thank you so much!!
Do you have a boyfriend…..
Tiger Man 😂😂 your names tiger man lol
mahi zen yes sir
Thanks so much for making this easy to understand!
Thanks a lot teacher!!!
How does she write backwards??
helped more than my irl teacher
Nice tutorial. Next, teach a derivation of the Good-Thomas FFT algorithm and watch the high-school students’ heads explode.
Mame you are so hot
I like you so much
Nancy is my hero. I swear there isn’t a mathy female in my entire state. She’s a true unicorn. Math people make me feel warm inside.
12:24 Are you actually allowed to do that last step? It feels wrong to me
interesting presentation method 😀
i’m sure she is not left handed xD
She is too hot
I know how you write backwards, im not gonna spoil it tho, just remember if you ever get married take your ring off before you record any vids thanx for your expertise
kidconfuzed I- I’m so confused…
@NancyPi, I’m impressed by how much info you include in the notes. Great job! I used to tutor math students, and saw so many people failing with the algebra. It’s nice to see you emphasizing those things. I always emphasized liberal use of parentheses to help students with sloppy habits.
Proud of you, keep going.
Excellent video helped me brush up on math I haven’t used in a long time…thanks, and keep up the great work Nancy.
What math class is it?
i didn’t even understad everything she said
Thanks so much, was having a hard time getting it but this helped a lot
Hi Nancy, on your second line, could the denominator be explained as being, Sqrt 2 x Sqrt 2 = Sqrt 4, which then equals 2?
Excellent explanation. Pleasant to hear your clear articulation. Good teachers are a great blessing.
first time in my live I see an angel teaching
Man… Our math teacher is hot….. Like extremely.
Math never looked so good. 👀
I am using parts of this video in my Algebra One course Nancy, your even and deliberate pace is perfect for a classroom activator! Thanks!!!
Chris West how to not do your job lol
Sometimes I wish I wasn’t in accelerated classes
Why are half of these comments about her looks?????
Nancy is best teacher compare to other youtuber teacher, her explanation is clear and clean.. shes the best!
I understand now! Thank you!
I still don’t get it!!💀💀
Nancy you are a natural teacher, you explain every detail.
I can’t figure out if she’s friendly by nature or just smirking at our dumbasses bc we didn’t pay attention in HS 🙂
She smirking 😂😂
Great video, thank you for the guide!
Yo I came here to learn about simplifying radicals
U guys notice that she writing backwards?
if I were a millionaire, would you be my personal tutor?
Thank you for making it so much easier to understand, I was so lost, this helped so much!
just subbed 😉
You helped me so much with my homework, it was a breeze. Thank you so much!!!!!! I subbed and hit that like button, Thanks!
Think I would have done better in math if she was my teacher
How tf she writing backwords so easily lmao
Mam your so beautiful
I watch this purely for asmr
@DeeCee Studios yeah but it’s called a comment section for a reason
@ZI TING ZHENG It’s not called cringe section for a reason
@One Two ???
@One Two L
OMG IS SHE WRITING BACKWARDS😄
Buggy 99 maybe but I feel like she just horizontally flips the recording after she’s finished as others have said.
@Cheese Cake it would flip her hand too no?
@Carlos Guzman that’s the point, she’s writing with her right hand, so when it is flipped it seems as though she is writing with her left hand
Hi, Nancy. When reporting the square root of ’16,’ why don’t you report ‘4’ and ‘-4’?
Your vids have helped me greatly. Thanks.
Thank you so much. This helped me a lot.
Cutest math helper online
This was so much more helpful than my teacher!! Thanks
Yo what is she writing on
Why isn’t my math teacher that hot 😂😂
edit your vids!!!
Wait for the last example there where only 2 terms being subtracted so it was easy to tell what the conjugate was what if u have 3 or more terms do u change all signs between numbers?
How does she record. My mind in fkd
i guess she is writing on a glass and then taking a mirrored image
Thanks i have a quiz tomorrow
Thank you so much! I really understand and love your voice. Very clear and doesn’t feel rushed.
This is the video that finally let this click for me. Thanks Nancy!
I was having trouble understanding how to simply radicals in geometry and this video was very helpful.
thank this will surely help me
Root signs cancel? It seems to me that you just multiply the numbers within the roots regardless of if they match or not. sqrt(3)*sqrt(3) = sqrt(9) which in turn equals 3. But if the problem were sqrt(2)*sqrt(3) = sqrt(6)
Is she writing inverse !?
I have no idea why my teacher thought this to us like we have done before. She didn’t explain in details
Thank you !! Now I can do my math homework easily
Can you cover more advanced topics such as Probability, Multi-Variate Calculus, etc .?
15:10 it’s faster to just use (a-b)(a+b) = (a²-b²)
better than my professor, i feel you are injecting math in my mind.
How does she write backward like that?
I swear Mrs.Nancy you just blessed me I almost gave up on math.
You make it fun for me by writing ✍️ in different color markers
Is it me or does Nancy seem like she is being forced to do this?
can you solve this for me?
5 divided by 2root7
5 root 7 over 14
You complete (…) me.
…the square for
You explain ok… but too slow
You can make the video speed faster 😅
You sound depressed lmao
Her voice is so relaxing
before watching this I was just a square.. but now i’m a perfect square
that was so beautiful
@Sarah Gomez .ook………k.k…..k..o..ok…k…….o.k..m.lk…….o.ok.k..k……….m…k…k..k..k…k…ko.o……l..o..l…..k.k.k…..o.o..o..k.k.k..o.
Great video, thank you
I would marry nancy lol 😅 pretty and smart
Dang, this is a radical video. #punny
Thank you so much 🙂
Hi Miss, how can i solve radicals to final answer with out any calculator?
Oh my god. Thank you so much. This was so clear and taught ne so well. I needed this information for an Algebra 1 test tommorow. I never even slightly understood what the teacher meant. This helped so much. Thank you so much.
please do more. you are a great teacher..
Such clarity! Thank you.
Lmao. You’re math is so good I decided to subscribe. And I never subscribe to teachers. Good job Nancy you deserve your subs!
Love ur teaching from India 😉😉
Got a math ad nice
shit i cant concentrate i wonder why
she hella cute no🧢
I always thought FOIL only works with quadratic equations.
come one guys just focus on math v r giving negative feed back to her
How is square root of 16 4? What happened to +- 4?
at 5:00, why not take sqrt(32) and use 16 in the perfect square table to get 4 * sqrt(2) quicker than the method you showed?
You can’t simplify radicals, we are too complex!
You’re an MIT grad? Insane.
Wait with the √32 you divided by 4 but why not choose to divide by 16 as 16 is larger and also divides equally? Any help? Thx
U r a really good teacher
Thanks helps me a lot#
You’re very smart not only you’re good at math but you can write with your left hand
Thanks NancyPi…you make it look easy….
This help a lot
Hi Nancy could you pls make videos about GMAT maths and quant section ?? It would be a great help ,,
You are a “pretty” good teacher ,,
I appreciate your great efforts,,
not all heros write backwards
I love you
OH MY GOD, this video is so helpful! 🙂 I’m a freshman in highschool, and I thought that I would never know how to simply radicals,:( but now I do! Thanks a lot NancyPi!!!!!
Do you have a video with variables and exponents?
5:20 “A big ugly number like 125”. Love these videos.
If I had this math teacher I’d pay attention every day in class. Not just because she’s beautiful, but because she’s so good at explaining that she deserves my respect. Thanks so much for the vid!
Thank you so much I have been struggling so much 😭 thank you again ❤️💜💙💚
How many clicked here because she was good looking? ME
Attractive x ASMR = Hard to concentrate
Easier method is to look for the highest perfect square that goes into it rather than the lowest because it becomes unnecessary to simplify it. Instead of starting with “4” for sqrt32 you should start with “16” (sqrt32 = sqrt16 x sqrt2 = 4 x sqrt2).
Oh my sweet Jesus…. Why can’t all my teachers be like you?
Van Halen says it best.
1:04 WOW! She knows to swallow without broadcasting it by smacking her lips!!!!
She keeps her expressions and movements to a minimum (even her lips while speaking,) uses her eyes to draw you back-and-forth from her face to her work while keeping her face focused on the board work, writes backwards legibly — ALL definite character traits of a public presenter.
Good job that proves she’s a trained orator.
Those in COMM classes that want a class-A example how to speak to the public efficiently should watch NancyPi’s videos.
Bad Habits – (which is surprising – considering her skill):Shows nervousness at the beginning of the video, but gets in her zone by 1:40 (this is when her bedroom-eyes kicks in), uses “Alright/Okay/Now/so” as bridges to start her points. Misplaces her smile when asks for your “like” at the end of the video. You can find the others. The presentation would still get an A- from my college-trained evaluation.
17:03 I am surprised (at how much I learned in 17 minutes that I didn’t in high school and college) that NancyPi did not point out that “23” is a prime number so that confirms the expression is in it’s simplest form.
I’ve just learned, (lonely heart distracting me included) more in 17 minutes that all the hours in high school and college. If only I had the wisdom now in my youth.
Thank u!!!!! I’m in algebra 3 and I got so messed up on theses
Prettiest girl ever
what if its asking for the square root as the product of two square roots?
5:00 Yep. I’m back. HOW can a person make “Four” sound so romantic?
capie44 did your nasty your like 60, ugly and fat.
@Hannski 1771 English, please.
give a resounding compliment…)
capie44 your like 60 she’s like 20. You are a weirdo and a loser
@Hannski 1771 : Welcome to your future 😘
Oh my God! I love you. Thank you!
Outstanding Thank You
Anyone else realized that she had to write all this stuff backwards, in order for us to see it normally? I find that impressive.
omg thank u so much i have watched so many videos and was still confused until i came across ur video. i finally understand it, honors geometry is a pain. thank u so much nancy<3
Anyone else say… Square root than radical?
sorry with all due respect it’s really hard to focus while watching her teach. No disrespect, just wanted to share my thought.
Nancy doesn’t get squared. She is a perfect 10!
are you writing backwards ??
Well, this is the first time I’ve subscribed to a math channel.
Thank you for the clear explanation
She makes more sense then my math teather 😑😂
Nancy, you make me crazy! I can not follow, because you are to pretty.
Can you come to my school and be my math teacher?
You are cute.
And this whole time I thought I was unreachable
Fantastic. can not thank you more!!
I Love You
Thanks I learned alot
So helpful! I wish I could send you a thank you basket or something.
the fact the she writes it from behind fucks with me anyone feelin that?
HOW ARE YOU WRITING BACKWARDS
When you started 0:44 I wrote the answers to the ones I KNEW how to do. When you got to 05:13 I was thinking “O.k. the next one is 7 times the square root of 7. When you wrote “125”, I could see the answer in my head, and was thinking, WHY did she change it from 343 to 125? ~ 0:44 You said you were going to show us how to multiply [5 times the Square Root of 54] TIMES [4 times the Square Root of 31], but at 10:00, you didn’t. I got the final answer of 3 times the Square Root of 186. Is this correct? ~ Since this was as far as I KNEW how to do, and since you didn’t show what you said you would show, I stopped watching at 10:07
Damn, I never knew about the perfect square. I use to think the number under the radical was difficult which I never finished. Thank you so much for explaining it in detail. My teacher rushes math in 4 hours!
thx thx a lot i have a test twommowro and now i understand it <3
Washington needs you!
She actually looks like spider mans aunt though.
I love how she’s writing all this backwards so neatly and I can barely write normally.
It gives me anxiety
Bruh stop w the ads bro I’m bout to fail a text😂
why did this help me more to understand than my teacher?? 😂
A reason to be happy that I’m quarantined 😂
Best teacher fam
Thank you for showing me how to do this
I’m in H Geometry doing an algebra 1 review and i couldn’t remember how to do this
Wouldn’t the square root of 6 simplify to 2 x 3 or something like that??
No, it just doesn’t *work* because nothing goes into 6 that is a *PERFECT* Square, -nor- 6 *isn’t* a *perfect Square* .
put it on 1.5 speed, thank me later 🙂
Math is so sexy
I don’t understand
Can you solve this question
Root 75_2 root 27 + 3 root 1/3
You are a great great tutor.Keep up.
Thank you so much. You have helped me out in algebra 2 so much. I appreciate what you are doing on YouTube. Keep up the great work
NancyPi: big ugly number
125: awh fml
can u tutor us
need help asap
Thank you sooooo much nanci
I understood the lesson from you
Thanks fot the video its really helps a lot I understand more with you than my college professor
This is an excellent tutorial, but I have to ask: are you writing numbers backwards on a glass screen to demonstrate?
Thank you for not assuming I knew what a perfect square is. Also I found you after getting thoroughly confused on Khan Academy. THANK YOU!
You’re gorgeous Nancy 😭😍
Xxcoolgamer xX how is complimenting a girl make me a simp? You clearly don’t have experience with them if you think what I did is simping.
ohh shittt, she has grey-blue eyes and is a lefty!!!!
yall best not be out here simpin or else some hands boutta be caught
17 min video which is surely better than a 2hour lecture. Appreciated :))
couldn’t wrap my head around knewton’s explanations. Was about to lose my mind. Your calm and steady voice did the trick. Hopefully i’ll be able to complete my assignments thanks to you
Are you Nancy 3.14?
Why isn’t it 1.7540…
Do you tutor? I live in Carson CA
Great vid, I understood immediately!
Oh my god I just learned at age what a square root.
how does she write backwards like that
Thank u so much
Thank u soooo much
8:36 Isn’t the square root of constant 9 both +and- 3?
But idk 😐
Normally, yes, but when simplifying radicals, you are only taking the positive root
How many tank tops she got
Thank you 😘 you help me I like your video ♥
and if there is 7) example
i mean what if with base there is a power (exponent) so as the power is on root (idk what it is called exactly )
i know you won’t reply or heart it but i don’t need it anyway please help me !! you can include it in one of your video and send me the link than you can delete your like your teaching is really good i can’t understand other than your teaching :(help me:)
thanks a lot
is nobody going to talk about how youre writing backwards
Thanks, Nancy Pi
U are cute
For some reason, I was struggling with this. Thank you NancyPi for explaining it in a way where I do get it now.
shes so beautiful because of her intelligence, but she is physically beautiful as well haha
Thanks so much for this I missed the day my teacher taught this lesson
i have watched so many videos of this and kept on getting it wrong, this was super helpful
I missed the week my teacher taught this lesson and my teacher isn’t good at explaining math so thank you so much
HOW CAN SHE READ AND WRITE BACKWARDS?? **IMPRESSED**
Nancy, this is amazing! Thank you so much! 🙂
would have been much simpler, and Nancy knows this, was to choose root 16 x root 2. root 16 gives you 4 root 2
root 2 x root 2 is root 4. 4 is a perfect square of 2, so you can drop the root symbol which just leaves 2.
I’m radically in love 🙂
Matthew Grooster and I’m radically calling the police
and yes the pink marker is an absolute necessity for Nancy.
root 3 x root 3 = root 9. 9 is perfect square of 3 so you can drop the root symbol.
Thank You !
Are u single?
Eu não sei oq eu tou fazendo aqui eu não falo inglês
📢you saved me ma’am 📢
Nancy … 10 10 10 10 10
before watching this I don’t like pie, but now I like Pi.
unrelated question : What technology or software you are using for making such interactive video in which you are writing on screen effect is there?
Surds are fun with Nancy! xx
if you were my Nath teacher I’d never miss school
Anyone here from Mrs. Surber’s math class?
Conner Beierle nah
The square root of 16 is plus or minus 4 not just positive 4. -4*-4 is also 16.
Did any of you even realize that she is also writing everything backwards so that the viewers can read it and see her face?
Maria Patricio I don’t think she is… maybe the camera was flipped or involved a mirror? haha
saved me as a new “homeschool teacher” for an 8th grader…..way too many years since my algebra days!
I think it did help understand a little bit more, but how do you do it with fraction??????and , say if five square root with 4 as an exponent??????
Nancy I love you will you marry me.. plz reply.. Nancy🥰
Pro i don’t know were should i loke
How is she in the board like that doe 🤯🤯
@16:32, why is it not 23+9 root 6 since we are just adding two root 3s? You wrote it as 23+9root3. How did you get the root 3? Love your videos by the way.
Really good video, explains really good
nancy, have i ever told you that you have a cute smile
I hate math >:(0
Thanks you so much, great lesson. Hey are you writing in mirror mode like Da Vinci?…far out!
Nancy is so good at communicating her subject , that I was finally able to see the light . Thank you Nancy!
You are the perfect combination of beauty and brains. You just won another subscriber. BIG THANK YOU!!!!!!
So much easier listening to a pretty girl lol unfortunately MATH AND PRETTY GIRLS 2020
“a big ugly number like 125”. lol
Well, most radicals (部首) are simplified either as comparisons to running script or by the transformation of the traditional character into something easier to write and hopefully symbolically evocative. If instead you mean simplification of a radical (部首) to its abbreviated form, in principle the abbreviated form retains the structure of the radical (部首) but with fewer and shorter strokes. If instead you mean calculus then I really can’t help you. Which is why I am watching this video instead of memorizing even more Chinese characters…
pointless 17 minute video on only the stupid easy math radicals you’ll never ever see on any math exam whatsoever. show the freaking hard stuff will you..!
This girl writes backwards and parts her hair on the wrong side.
Thanks a lot…👍🏽👍🏽⚘
having to watch these during corona bc my teacher didn’t put notes 😂
Andre Boudreaux same
Andre Boudreaux ikr
I always associated math tutors with the Big Bang Theory kind of people. She is the heck of the exception to the rule.
Put the video at 1.5x speed so you don’t have to deal with the pauses. helpful video
Thank you so much. I am online, and this was one of the hardest lessons. I googled for help, and I came to this video. Understood it in a few minutes, rather than hours. You are a life saver. <3 Have a good day.
I love the fact she’s talking slowly so we can understand her better,must be painful.
very good info
and THAT! is how you teach. (for all the powerpoint and paint creators)
Thank youuu!!!! 🙂
niggas do be simpin tho
Hi dear Nancy. I always admire the way you teach but why I feel you are tired or loose confidence in this lecture. Any how Keep it up you are doing great job.
Super helpful now I don’t have to go into a stupid zoom meeting to ask for help
My favorite algerba teacher, and the prettiest professor
I really love Nancy teaches she has a wonderful calm voice that instantly draws you in to the end. She has a very great vibe that she spreads out. If she had a class i would definitely take her class.
Thanks this helped a lot👍
Thankyou NancyPi your explanations helping out with my assignment.
What if I have a variable
You are so awesome..thank you
Nancy you suck
Why is her voice so relaxing
this VIDEO FUCKING sucKS!!!!
she has a soothing voice.. please don’t put me to sleep, ma’am
I just come to see the teacher … Good morning Nancy.
Arturo Martinez dude wtf
I learned this a while back and forgot the process, but you easily jogged my memory! Thank you!
can I just say she looks like Hannah Brown?
wow math was just booring af but thanxs nancy nobel prize awards will choose u
Only confusing thing is how you managed to right the way you did
I LIKE MATH NOW BECAUSE OF YOU
thank youuuuu, you help me with my exam!!
Are you lefty???
nice explanation ..!!!
Litteraly saved me like 2 minutes before a test so thanks so much
Super knowledge and presentation.
Is Nancy left-handed? I’m right-handed.
I really appreciate your method of teaching math. Please, keep it up.
She helped me learn so much and she’s so pretty
Sorry Nancy, if my comment hurts u in advance but surely it’s makes your work little easy and more lucid
If u want to get square root of any number in simplest form ..
Just write the number in prime factorization form and than u will get what I want
Use little algebra while solving denominator , like “ (a +b) (a-b) = a^2 -b^2.
OMG the numbers are floating :O
studying for the asvab over here and im happy i found this beautiful math teacher. had me refresh my math easier than i remembered in high school
I wished you were my teacher! You teach this lesson really good!
It’s more impressive how well she can write backwards
😮 it’s amazing
Oh my God
188 dislikes, 188 people who may have been dropped at some point.
SUPER GOOD EXPLANATION! I must admit, you are better than my teacher.
I like both
You’re a math goddess
Kinda late…. school is over now.
How to make you this video
Your brain is so hot.
Wish she was my math teacher lmao
NANCY, WHHY IS YOUR VOICE SO AWESOME?! LSKDFJDCCV
Are you writing on the camrta?
Hi Nancy really impressed with yur presentations pls guide me how your write inverted I mean you write and its looks right ok for the viewer HOW?
And second how you mange to fast forward your subtlewritings?
what application did you use? writing on glass?
shes seems stressed
do u have any idea how much u r doing for me rn u beautiful queen
Was she being held hostage when making this video?
You are beautiful….
you look little bit confuse
ok so what if I have to square 448? then I end up with square root 8 and then square root 8 again and square root of 7 and I end up with a bunch of square root 2’s and 4’s and now I am confused…
why she write a . for times
This was the most helpful video I have found on this topic and I have been looking for a long time, and I did not understand a thing thank you so much
I like maths b/c of u
i hate geometry
She does more talking than work
Thank you so much for your video. Finally I’m starting to understand the concept. Thank you for breaking it down and taking the tome to explain each step slowly and clearly.
Yeeeeeeees its good
Monstrous effort, thank you Nancy!
Very nice video tutorials NancyPi… you are excellent…
I like you and your videos darling…
Love your show. Very strait forward.
I give you my like and my heart
how come when you added 4 sqrt 3 + 5 sqrt 3 it was 9 sqrt 3 instead of 9 sqrt 6? i thought if you added to squares together then normal rules of addition apply?
Thanks Nancy I have understood your lesson 100%
when doing radicals how do I get a byproduct and what do I do with it?
how do I find the square root of 17 and get 4+1/8+1/8+1/8+1/8… ?
