    Differentiation help <URGENT>

    I have two functions to differentiate.

    1) 2x(x+4)^8

    2) x/(x+2)^2

    If possible, please include step-by-step instructions.

    1. [tex] f(x) = {2x(x+4)^{8}} [/tex]

    Have you tried using the product rule?




    2. [tex] f(x) = \frac{x}{(x+2)^{2}} [/tex]

    Have you tried using the quotient rule?

    Make sure that you understand the chain rule for #1, if you don't know how to apply it in your sleep yet, keep practicing.
