What is the square root of 72, in simplified ratical form?

Question

I am soooo bad with math, and cant seem to understand square roots.

Thanks so much!

Answer 1

6 sqrt(2)

Answer 2

Square Root Of 72

Answer 3

You can split the root into factors (36x2=72). Notice 36 is a perfect square. Root 36 times root 2 = 6 root 2.

Answer 4

sqrt (72)= sqrt (8*9) you can break up the number in thesqrt into smaller ones that have perfect square roots. to get:

=sqrt (4*2*9) now you can take the individual square roots and leave the ones that dont have a nice root under the radical.

= 2*3*sqrt 2= 6 radical 2 ( the 4 & 9 had nice roots of 2 &3)

Answer 6

First, find out what numbers can multiply to equal 72

√72 = √9*8

Then find other numbers which can be squarerooted and will get you a whole number
= √9*4*2

= √9 * √4 * √2

= 3* 2 * √2

=6√2

Answer 7

sqrt(72) = srqt(9*4*2) then you just simplify

take sqrt of 9 & 4, which is 3 & 2, then multiply then together = 6

leave the 2 under the radical because it is not a perfect square

which gives you the answer

6 * sqrt(2)

Answer 8

Why so complicated? She was asking for simple. 8 times 8 equals 64. So short of the answer. 9 times 9 equals 81, greater than then what she was looking for. So if you diligently but break it up, 8.5 times 8.5 equals 72.25 so just slightly off. It can be found on calculators by just typing 72, and pressing the symbol for "root" The answer is 8.485!

Answer 9

sqrt of 8 times the sqrt of 9
= 2 times 3 sqrt of 2
= 6 sqrt of 2
use the symbol for sqrt

Answer 10

I know this is 7 years later but the answer is actually 6 square root 3

Answer 11

nooooo, it is not 6 root 3, its 6 root 2
