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!
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?
