Question

Is this two chain rule problems together or would you use the product rule on this or what?
Find g '(x) if g(x)=(x+1)^2(x^2+1)^-3

Answer 1

Use the derivative of a fraction rule.

Answer 2

This might make me look stupid, but I don't see a fraction. What am I missing?

Answer 3

first, product rule, then chain rule or the fraction rule that is
\[g(x)=f(x) / h(x)\]
\[g'(x)= \frac{ f'(x)h(x)-h'(x)f(x) }{ h^2(x) }\]
but remember to use the chain rule too for the derivatives, by the way
x^-3=1/x^3 xD
