calculus - Find derivative of function

I need help in finding the derivative. I don't even know where to begin with it. I'm learning chain rule in school and do not see how I can apply that here.

$$
f(x)=\left(\dfrac {x+1}{x^2+8}\right)^6
$$

Any help would be appreciated!

Answer

HINT: If $g(x)=(h(x))^n$, then the Chain Rule implies that $$g'(x)=n(h(x))^{n-1}\cdot h'(x).$$
