WEBSep 7, 2022 · The chain rule combines with the power rule to form a new rule: If \(h(x)=\big(g(x)\big)^n\), then \(h'(x)=n\big(g(x)\big)^{n−1}\cdot g'(x)\). When applied to the composition of three functions, the chain rule can be expressed as follows: If \(h(x)=f\Big(g\big(k(x)\big)\Big),\) then \(h'(x)=f'\Big(g\big(k(x)\big)\Big)\cdot …
