Best ResponseYou've already chosen the best response.1I 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.

Best ResponseYou've already chosen the best response.1The 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.

Best ResponseYou've already chosen the best response.1If it is hard for you to see the constant kainui got. You can look at a an example with a lesser power

Best ResponseYou've already chosen the best response.1Like what would f^(4)(x) look like if we had f(x)=x^5

Best ResponseYou've already chosen the best response.1So does the limit even exist?

Best ResponseYou've already chosen the best response.1\[\frac{ d^n }{ dx^n }(x^n)=n!\] just for fun  Yeah, it even exists and it's even zero. @jennisicle
