Please use the ^ sign to show powers. Otherwise, it can get confusing. =)

As a general rule, when deriving:

$\displaystyle \frac{d}{dx}\ x^n$ = $\displaystyle n x^{n-1}$

So use that to find the derivative of $\displaystyle x^5$.

If your second derivative is $\displaystyle e^{lnx}$, then you can simplify it by remembering that $\displaystyle e^{lnx}\ =\ x$
