Question 9ciii HSC 2004 (1 Viewer)

The question required $e^x \geq x^e \text{ for }x>0$

So i got up to $e^x \geq e^{elnx}$

I'm pretty sure that's right and now I don't know how to get to $x^e \text{ from }e^{elnx}$

thanks.

$e^{elnx} = e^{lnx^e}($as $alnb = ln(b^a))\\\\ ~~~~~~~~~~~= x^e ($as $e^{lna} = a)$

After all that it was really simple haha. thanks.
