Question

Rewrite the radical expression as an expression with rational exponents.

cube root of x to the power of 8

Answer 1

Explanation:

`\sqrt[3]{x^8}=x^{(8)/(3)` The little number outside is called the index and that always serves as the denominator in the rational exponent. The power on the radicand (the radicand is whatever is inside the radical) serves as the numerator.
