That seems good to me but I'm kind of tired.
How would you solve:
((25x^3)^(2/3))) / ((125xy^2)^(1/3)))
I got the cube root of 625x^6 in the numerator and the cube root of 125xy^2 in the denominator.
After I simplified them, I got 5x^2 * (cube root of 5) in the numerator and 5(xy^2)^(1/3) in the denominator, but that doesn't look right to me.
