Answer 1

Answer: A

Explanation:

A fractional exponent can be written as a number with a radical to the power of the denominator raised to the power of the numerator. It sounds difficult, but is really very easy.

`x^{(4)/(13) } =\sqrt[13]{x^(4) } \\x^{(7)/(3) } =\sqrt[3]{x^(7) } \\`

Thus, the answer is A

Answer 2

`\sqrt[5]{2^3}`

Explanation:

2 is the base

The top of the fraction is the power

The bottom of the fraction is the root

`\sqrt[5]{2^3}`
