\frac{d}{d x} (\frac{e ^{x}}{7 + e ^{x}})

\frac{7 e ^{x}}{( 7 + e ^{x} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{e ^{x}}{7 + e ^{x}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( e ^{x} ) ( 7 + e ^{x} ) - \frac{d}{d x} ( 7 + e ^{x} ) e ^{x}}{( 7 + e ^{x} ) ^{2}}

\frac{d}{d x} (e^{x}) = e^{x}

\frac{d}{d x} (7 + e^{x}) = e^{x}

= \frac{e ^{x} ( 7 + e ^{x} ) - e ^{x} e ^{x}}{( 7 + e ^{x} ) ^{2}}

Simplify

\frac{e ^{x} ( 7 + e ^{x} ) - e ^{x} e ^{x}}{( 7 + e ^{x} ) ^{2}} : \frac{7 e ^{x}}{( 7 + e ^{x} ) ^{2}}

= \frac{7 e ^{x}}{( 7 + e ^{x} ) ^{2}}
