derivative of

ln (x + 4)

\frac{1}{2 ( x + 4 )}

Solution steps

\frac{d}{d x} (ln (x + 4))

Apply the chain rule:

\frac{1}{x + 4} \frac{d}{d x} (x + 4)

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

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

= \frac{1}{x + 4} \cdot \frac{1}{2 x + 4}

Simplify

\frac{1}{x + 4} \cdot \frac{1}{2 x + 4} : \frac{1}{2 ( x + 4 )}

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