How do I differentiate 2x(x+4)^8 and x/(x+2)^2?

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. $$f(x) = {2x(x+4)^{8}}$$

Have you tried using the product rule?

2. $$f(x) = \frac{x}{(x+2)^{2}}$$

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.
