derivative of ln(21x)

Lösung

\frac{d}{d x} (ln (21 x))

\frac{1}{x}

Schritte zur Lösung

\frac{d}{d x} (ln (21 x))

Wende die Kettenregel an:

\frac{1}{21 x} \frac{d}{d x} (21 x)

= \frac{1}{21 x} \frac{d}{d x} (21 x)

\frac{d}{d x} (21 x) = 21

= \frac{1}{21 x} \cdot 21

Vereinfache

\frac{1}{21 x} \cdot 21 : \frac{1}{x}

= \frac{1}{x}
