CPM Homework Help : CALC Problem 6-64

Let $f(x) = e^x$ , so that $f^{−1} (x) =\operatorname{ln}(x)$ . Write an expression that represents each of the expressions below, then simplify.

$f(f^{−1}(x))$
Hint (a):
Do you remember the definition of inverse functions?
$f(x)$ and $g(x)$ are inverses if $f(g(x)) = x...$
Well, $f(f^{−1}(x)) = e^{\operatorname{ln}x} =$ ______
