    Show some work first and indicate where you got stuck.

    Not to sound too harsh, but if you can't even do a derivative as simple as xlnx, you won't do well on tomorrow's exam. Try reviewing:

    (1) product rule
    (2) quotient rule
    (3) chain rule

    Once you do so, the question you asked should be easy to solve.

    Hi Penultimate! :wink:

    It must mean the fifth derivative, ie the derivative of the fourth derivative, ie … d/dx( d/dx( d/dx( d/dx( d/dx(xlnx))))).

    How far have you got? :smile:
