Logarithmic differentiation

  1. Jun 19, 2008 #1
    Question:
    Find derivative of f(x)=((x^2)(x^3))/((x^4)(x^2))
    Attempt:
    ln f(x)=(lnx^2)+(lnx^3)-(lnx^4)-(lnx^2)
    Can someone tell me what I have done wrong so far?
    Thanks

    Why don't you just simplify and then differentiate?

    I did take the log of both sides. I'm doing it this way because i need to learn this method of differentiation.
