Question 887288

y{cubed root(81x^2)}-{cubed root(24x^2y^3)}

I know that 3x^2 will go into both, but i'm not sure how to get the final answer. I think the answer would by y{cube root(3x^2)}, but I'm confused on how to solve these types of problems. Thanks SO much in advance!!

{{{y*root(3, 81x^2) - root(3, 24x^2y^3)}}}
{{{y*root(3, 3^3*3x^2) - root(3, 2^3*3x^2y^3)}}}
{{{3y*root(3, 3x^2) - 2y*root(3, 3x^2)}}}
{{{highlight_green(highlight_green(y*root(3, 3x^2)))}}}
