Answer

inside: $g(x)=x^5-1$ outside: $f(g) =3g^{-3}$ derivative: $f'(x)=-9(x^5-1)^{-4}*5x^4$

Work Step by Step

Rewrite the function as $3(x^5-1)^{-3}$ Use the chain rule to take the derivative $\frac{d}{dx}f(g(x))=f'(g(x))g'(x)$ To find the inside, you take the number inside the parenthesis. To find the outside, you exchange the parenthesis to a variable. Then take its derivative and put it together.
