So I'm trying to do my homework on L'Hopital's rule. There's this one problem I have to do where I have to find the limit as x approaches negative infinity of (x^4)(e^x). How do I do this, since it's not in the form f(x)/g(x)? Thanks

Another one I'm not sure about is the limit as x approaches infinity of (x^2)/lnx I took the derivative of the top and bottom and got 2x/(1/x) which is the same thing as 2x^2. Can I keep going or do I just say that the limit does not exist?
