derivative of

ln (\frac{4 x + 1}{2 x - 7})

- \frac{30}{( 4 x + 1 ) ( 2 x - 7 )}

Solution steps

\frac{d}{d x} (ln (\frac{4 x + 1}{2 x - 7}))

Apply the chain rule:

\frac{1}{\frac{4 x + 1}{2 x - 7}} \frac{d}{d x} (\frac{4 x + 1}{2 x - 7})

= \frac{1}{\frac{4 x + 1}{2 x - 7}} \frac{d}{d x} (\frac{4 x + 1}{2 x - 7})

\frac{d}{d x} (\frac{4 x + 1}{2 x - 7}) = - \frac{30}{( 2 x - 7 ) ^{2}}

= \frac{1}{\frac{4 x + 1}{2 x - 7}} (- \frac{30}{( 2 x - 7 ) ^{2}})

Simplify

\frac{1}{\frac{4 x + 1}{2 x - 7}} (- \frac{30}{( 2 x - 7 ) ^{2}}) : - \frac{30}{( 4 x + 1 ) ( 2 x - 7 )}

= - \frac{30}{( 4 x + 1 ) ( 2 x - 7 )}
