(\partial)/(\partial x)(ln((y^9)/(x^7)))

Lösung

\frac{\partial}{\partial x} (ln (\frac{y ^{9}}{x ^{7}}))

- \frac{7}{x}

Schritte zur Lösung

\frac{\partial}{\partial x} (ln (\frac{y ^{9}}{x ^{7}}))

Behandle

y

als Konstante

Wende die Kettenregel an:

\frac{1}{\frac{y ^{9}}{x ^{7}}} \frac{\partial}{\partial x} (\frac{y ^{9}}{x ^{7}})

= \frac{1}{\frac{y ^{9}}{x ^{7}}} \frac{\partial}{\partial x} (\frac{y ^{9}}{x ^{7}})

\frac{\partial}{\partial x} (\frac{y ^{9}}{x ^{7}}) = - \frac{7 y ^{9}}{x ^{8}}

= \frac{1}{\frac{y ^{9}}{x ^{7}}} (- \frac{7 y ^{9}}{x ^{8}})

Vereinfache

\frac{1}{\frac{y ^{9}}{x ^{7}}} (- \frac{7 y ^{9}}{x ^{8}}) : - \frac{7}{x}

= - \frac{7}{x}

x \to 0 lim (+ (\frac{ln ( x )}{x}))
