In this video we'll learn how to divide one radical by another radical. This is the same as having a fraction in which both the numerator and denominator are square roots.
When the numerator and denominator are separate square roots, we can put the whole fraction under one square root, reduce the fraction to its lowest terms, and then take the square root of the remaining numerator and denominator.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student-from basic middle school classes to advanced college calculus-figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

Bless RUclips mathematicians, most useful resource for nerds to ever exist on this site :D
Hey Krista! It's been awhile. Nice video as usual :) My students like the "factor tree" method of breaking down radicals as opposed to finding the hidden perfect square. The factor tree method also lends itself to simplifying when using a different index for cube roots, fourth roots, etc. Fun stuff!
+Kevin Vines Love that. I'll have to add a video right after this one with the factor tree method to show people that alternative. Thanks Kevin! :D
Oh my goodness ❤❤ where have you been?!
1. I haven’t slept well in a week now, and your voice truly made me so relaxed and I fell asleep 😂😂
2. I fell asleep bc I love math and science. While not the fastest learner, I know a final answer exists and obsess until it’s solved…. These lessons are well understood so it’s like watching a favorite comforting movie to sleep
This is maybe the best video I’ve ever heard
Awww thank you so much!! I love that math always has a right answer, too. Something very comforting about that. ☺️ I’m so glad the video was relaxing, should I try math ASMR?!! 🥱🥱😝😝
@@kristakingmath Krista seriously…. I just love math and science and nothing has been more relaxing. I had a bad car accident and I’m going to be good but been a tough few months
The ability to relax without medicine the last few nights has been just 😍🫠
@@kristakingmath and yes you should!! Don’t have to change your format at all, but just being conscious of noises and writing! It’s like unexpected asmr!
Just don’t start a video about the 3x + 1 problem 😂😂 I’ll never sleep
Very clear and easy to understand. However, I don't understand why the product of the two square roots (denominators) equals a whole number and not a radical, like when multiplying any other square roots together. Trying to find answer....
What if there’s a binomial such as x/sqrt(x^3+4x).
Amazing Video! Rly helped me :)
Glad to hear it, Neev! :)
why do we not want to leave the square root at the denominator?
If we always rationalize the denominator, then it makes it way easier to compare the values of different fractions. :)
@@kristakingmath thanks for the clarification :D
what if the denomintor has another constant with it?
+Warlock vs Marlock You can pull that constant out. For example, if there's another 2 in the denominator, then you call pull it out of the fraction as 1/2, then do your simplification with the square roots, and then bring the 1/2 back into your answer.
So you can leave a square root in the numerator
