so x^(1/3) = cuberoot of x
what does x^(2/3) = as a radical?
How would I go about cancelling x^(2/3), or rather what is the opposite function of x^(2/3)?

Think about the laws of indices: . Does that help?
By "opposite function", do you mean inverse? In that case, it's the same as for any other function: You want to reflect in the line y = x. In particular, for any function of the form (if you're not comfortable with the notation, pretend I wrote instead of ), the inverse is of the form .
