Remove all perfect squares from inside the square root.
√72 =

5√2 or 3 and 2

Step-by-step explanation:

You would bring it down for 9 and 8 which would be 72

Then you would get a perfect square of 9 which would be 3

Then you would do 4*2 which would be 8 so you would divide 4 by 2 which would be two which would be another perfect score.

So then you would add them which would be 5 then you get the leftover 2 and make 5√2

But your perfect squares are 3 and 2
