Answer 1

The answer is C
You raise the number to the power of the numerator, and put it to the root of the number on the denominator.

Look at the attached image.

Answer 2

Rational exponents work like this: if you raise the number x to the p/q power, i.e.
`x^{(p)/(q)}`, you're considering the q-th root of x to the power of p.

So, in your case,
`x^{(2)/(3)}` means the cubic root of x squared.
