Homework Help: Finding a limit

  1. Mar 27, 2007 #1
    1. The problem statement, all variables and given/known data
    find the limit:

    lim (lnx)^3 / x
    x-->(infinity)


    2. Relevant equations
    It's a L´hospital homework so that should be what I need to use.


    3. The attempt at a solution
    However, when using L'Hospital, I get nowhere since I keep getting indeterminations.
    Help is appreciated.

    You'll have to repeatedly use L'Hopital until you get to a non-indeterminant. Takes 4 times, I think.

    Nasty how? It's just a little repetitious.
