a When we have a power raised to a fraction you can rearrange this expression by writing the exponent as a product, and then pull out one of the factors as an exponent.
Whenever you have a rational exponent with a numerator of 1, you can rewrite this as a radical where the fraction's denominator becomes the radical's index.
