Wolfram alpha tells me that $a^{1/\ln a} = e$ (Symbolab tells me it the LHS cannot be simplified).
Can you help me show this equivalence?

The best way is to convert everything to the same base, and the natural base is $e$. We write $$ a^{1 / \ln(a)} = \exp(\ln(a^{1/\ln(a)})) = \exp\left( \frac{1}{\ln(a)} \cdot \ln(a) \right) = \exp(1) . $$ The key fact is that for any real $x$, we can always write $x = e^{\ln(x)}$ since $x \mapsto \exp(x)$ and $x \mapsto \ln(x)$ are inverses.
