Question

how do i simplify this

Answer 1

\[\sqrt[3]{\frac{ 162x ^{6}+27x ^{3} }{ (27y ^{-3})^{2} }}\]

Answer 2

You can factor 27 from the numerator first. Remember, 27=3^3

Answer 3

but later I have to square it right?

Answer 4

Squaring 3^3 is easier than squaring 27, so you could do it immediately

\[(a^n)^m=a^{nm}\]
