Limit of (E^x+1)^1/x

  1. Jun 12, 2009 #1
    1. The problem statement, all variables and given/known data

    Lim (E^x-1)^(1/x)
    x->Infinito

    L'Hospital?

    2. Relevant equations

    Lim (1+1/x)^x=E
    x->Infinito

    3. The attempt at a solution

    Help!

    If you want to use l'Hopital you will have to take the logarithm of the limit first. Remember [itex]e^{\ln x} =x[/itex] and don't forget to show us your work!

    Thank you very much for your advice.

    I'm still unsure how to approach this one. Apply Ln() to the entire limit?

    Yes write the limit as [itex]\exp(\ln[(e^x-1)^{(1/x)}])[/itex].
