Question

find the derivative of the function y=ln(2x^8+9x)^9/7

Answer 1

use the chain rule
\(\bf \large {
\cfrac{d}{dx}\left[{\color{brown}{ ln({\color{blue}{ 2x^8+9x}})^{\frac{9}{7}}}}\right]\implies \cfrac{d}{dx}[{\color{brown}{ \square^{\frac{9}{7}} }}]\cdot \cfrac{d}{dx}[{\color{blue}{ \square }}]
