Express cube root 27x^4y^6 using rational exponents
(27x^4y^6)1/3
(27^1/3)(x^4/3)(y^6/3)
stuck. I think the final answer is 9x^3/4(y^2) I don't know where to put the parentheses to break it up so I hope yall understand what it's suppose to be.

it is wrong. What is the cube root of 27? Hint, it is not 9.
Secondly, the cube root of x^4 is x^(4/3)
