1. The problem statement, all variables and given/known data I have to prove that the limit as n ⇒ ∞ of: n(a1/n-1) = log(a) -> For every a >0 2. Relevant equations I have no idea what to use 3. The attempt at a solution This was an exam question i left it blank, because i had (and have) no idea on where to even start, i've tried using integrals/antiderivatives, but i didnt seem to get anywhere, this part of the exam was about derivatives, antiderivateves, integrals and fundamental calculus theorems (which we use to plot functions, so i dont see this one applying here) I know that if i set "a" as 1 that checks out, but that doesnt prove anything... ive thought about using the left side of the equation as an exponent to "e" and setting it as equal to "a" but i dont see that helping. What am i supposed to use to prove this?
