Natural Logarithm Derivative question

  1. Nov 18, 2006 #1
    Hi all,

    I'm a bit puzzled by one of my homework questions. I got an answer, but I have nothing to check it with and I'm not sure that my answer is correct.

    The question states that y=ln(ln(ln(x))), and asks for y'. This is what I've done, but it seems a bit too simple to me.


    If someone could tell me if the answer is right or wrong (and preferably why its wrong), that'd be very much appreciated.
