\frac{d}{d x} (\frac{ln ( 7 x )}{7 x})

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

Solution steps

\frac{d}{d x} (\frac{ln ( 7 x )}{7 x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{7} \frac{d}{d x} (\frac{ln ( 7 x )}{x})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{1}{7} \cdot \frac{\frac{d}{d x} ( ln ( 7 x ) ) x - \frac{d x}{d x} ln ( 7 x )}{x ^{2}}

\frac{d}{d x} (ln (7 x)) = \frac{1}{x}

\frac{d x}{d x} = 1

= \frac{1}{7} \cdot \frac{\frac{1}{x} x - 1 \cdot ln ( 7 x )}{x ^{2}}

Simplify

\frac{1}{7} \cdot \frac{\frac{1}{x} x - 1 \cdot ln ( 7 x )}{x ^{2}} : \frac{1 - ln ( 7 x )}{7 x ^{2}}

= \frac{1 - ln ( 7 x )}{7 x ^{2}}
