derivative of (3+2x/(5-8x))

Lösung

\frac{d}{d x} (\frac{3 + 2 x}{5 - 8 x})

Lösung

\frac{34}{( 5 - 8 x ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{3 + 2 x}{5 - 8 x})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( 3 + 2 x ) ( 5 - 8 x ) - \frac{d}{d x} ( 5 - 8 x ) ( 3 + 2 x )}{( 5 - 8 x ) ^{2}}

\frac{d}{d x} (3 + 2 x) = 2

\frac{d}{d x} (5 - 8 x) = - 8

= \frac{2 ( 5 - 8 x ) - ( - 8 ) ( 3 + 2 x )}{( 5 - 8 x ) ^{2}}

Vereinfache

\frac{2 ( 5 - 8 x ) - ( - 8 ) ( 3 + 2 x )}{( 5 - 8 x ) ^{2}} : \frac{34}{( 5 - 8 x ) ^{2}}

= \frac{34}{( 5 - 8 x ) ^{2}}
