convert expression $\frac{x^n}{2^{n^2}}$ to get rid of squared term?

Question

In an expression if we have $x^n$ divided by $2^{n^2}$ i.e $2$ raised to $n$ squared how can we get rid of the square term for 2?

Essentially want to get rid of the asymmetry and express the whole thing in n terms or $n^2$ terms for both x and 2.
