Question

How do you simplify `b^(-1/3)`?

Answer 1

Recall that `x^-n = 1/x^n` and `x^(1/n) = root(n)x`

Explanation:

First we can remove the `-` exponent, the expression becomes `1/b^(1/3)`, now we can simplify by representing the fractional exponent as a root, `1/root(3)b`

The simplified form is `1/root(3)b`
