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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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