aquires the indeterminate form, . So I would suggest the use of L' Hopital's rule.

Not to dissuade you from trying this, but I don't think L'Hopital's will help here. First off, it is of indeterminate form . Furthermore, since these are all exponential functions, they will all reappear when applying L'Hopital's rule, and will only be multiplied by constants, so you will still have an indeterminate form. WolframAlpha doesn't show the steps, unfortunately.
