I think the answer is supposed to be zero but how I get there?

I took the deribative of the top and the bottom but I just ended up at (100n^99)/(e^n) and don't know where to go from here.

You should see a pattern in the derivatives.

You could have left it. Maybe it is hard for some people to reach that.

The point is, L'H rule says the limit of a ratio is the same as the limit of the ratio of their derivatives as well. So we can just see that eventually n^100 will eventually become a constant while the bottom will always be a function of n.

If it is hard for you to see the constant kainui got. You can look at a an example with a lesser power

Like what would f^(4)(x) look like if we had f(x)=x^5

So does the limit even exist?

\[\frac{ d^n }{ dx^n }(x^n)=n!\] just for fun  Yeah, it even exists and it's even zero. @jennisicle
