derivative of ln(8x+7)

Lösung

\frac{d}{d x} (ln (8 x + 7))

\frac{8}{8 x + 7}

Schritte zur Lösung

\frac{d}{d x} (ln (8 x + 7))

Wende die Kettenregel an:

\frac{1}{8 x + 7} \frac{d}{d x} (8 x + 7)

= \frac{1}{8 x + 7} \frac{d}{d x} (8 x + 7)

\frac{d}{d x} (8 x + 7) = 8

= \frac{1}{8 x + 7} \cdot 8

Vereinfache

\frac{1}{8 x + 7} \cdot 8 : \frac{8}{8 x + 7}

= \frac{8}{8 x + 7}

\int \frac{20}{e ^{\frac{x}{5}}} d x

d er i v a t i v e f (x) = \frac{12 - 8 x}{5 x ^{\frac{2}{5}}}

\int \frac{x ^{2} - 81}{x} d x

\int \frac{( x ^{2} - 1 )}{( x ^{2} + 1 ) ( x - 2 )} d x

\frac{\partial}{\partial x} (\frac{5 x - 3 y}{5 x + 3 y})
