Apply L'hôpital's Rule until you get something except the indeterminate form. You should also stop when you get or too.
I need to apply L'hopital's rule as x approaches infinity for the following:
(e^2x)/((x+5)^3)
which gives me:
(2e^2x)/((x+5)^3) - (3e^2x)/((x+5)^4)
and a second time gives me:
(4e^2x)/((x+5)^3) - (12e^2x)/((X+5)^4) + (12e^2x)/((X+5)^5)
I guess my question is, how do I know when to stop (i.e. when have I found the limit as x approaches infinity with L'Hopital's rule?)

Hello, pennydooodle!
You don't seem to have a grip on L'Hopital's Rule . . .
You seem to be using some kind of strange Quotient Rule here . . .Apply L'Hopital's Rule: .
Differentiate the numerator: .
Differentiate the denominator: .
. . Then: .
Apply L'Hopital again.
