How can one prove that $e^\pi>\pi^e$ ? Should I use logarithms or something like that? Or is there a gentle smart way of proving so?

Hint:
$e^n>1+n$ given $n>0$. Now see what happens when $n=\dfrac \pi e-1$.

$n$ seems an un-natural choice of variable, no? (+1 though) – anaconda Apr 17 '14 at 18:08

@anaconda Un-natural? Really? :p – Hakim Apr 17 '14 at 18:15

Yeah, I thought it would be a good pun as well as a good point :) – anaconda Apr 17 '14 at 18:23
