Step-by-step explanation:
The expression given is inside a cube root. This is a simplified version of a fractional exponent, 1/3.
We can take the expression outside of the radical to get this:
3 ^ 9 ^ (1/3)
When an exponent is raised to another exponent, multiply the exponents and keep the base the same:
3 ^ (9 * 1/3)
3 ^ 3
The expression is equal to 27.
