Question

PLEASE HELP! I need to simplify the following equation. I will write in in the comments.

Answer 1

\[\frac{ 120r ^{3} }{ \sqrt{16r ^{9}} }\]

Answer 2

I know the square root of 16 is 4, and that there cannot be a radical in the denominator. But after that, I am lost

Answer 3

so, first off, take 16 out and cancel with 120 from numerator, what do you have? for number only, I don't indicate to r yet
