How do you convert a radical expression to a rational exponent and vice versa?

Take the expression x^2/3 which has an exponent of 2/3. The top of the fraction refers to the power - that is x^2 (x squared). and the 3 indicates a cubic root.

So in radical form it is ∛ (x^2)

Converting radical to exponent an example would be

∛ (x^5) = x^ (5/3)
