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)=(x+1x2+8)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))n1h(x).
