1. The problem statement, all variables and given/known data

Expand the fraction $$\frac{1}{\sqrt[n]{2^5}}$$, for $$n \in \mathbb{N}$$ and $$n \geq 2$$, to have denominator 2.

2. Relevant equations

3. The attempt at a solution

$$\frac{1}{\sqrt[n]{2^5}} \circ \frac{\sqrt[n]{{2}^{n-5}}}{\sqrt[n]{{2}^{n-5}}}$$

$$\frac{\sqrt[n]{{2}^{n-5}}}{2}$$

Is this correct?

Yeah it appears ok. Odd question, though.
