# You had "2^(2/3) = 4^(1/3) = cube root of (4)"

You had "2^(2/3) = 4^(1/3) = cube root of (4)"

It looks like you did 2^2 first and then did the 1/3 power. This is 100% correct. However, if we had a case where we had a perfect square or perfect cube, could we have take the denominator root first? Why?
