derivative of 1/(x(ln(x)^3))

Lösung

\frac{d}{d x} (\frac{1}{x ( ln ( x ) ) ^{3}})

- \frac{ln ( x ) + 3}{x ^{2} ln ^{4} ( x )}

Schritte zur Lösung

\frac{d}{d x} (\frac{1}{x ( ln ( x ) ) ^{3}})

Wende Exponentenregel an:

\frac{1}{a} = a^{- 1}

= \frac{d}{d x} ((x (ln (x))^{3})^{- 1})

Wende die Kettenregel an:

- \frac{1}{( x ( ln ( x ) ) ^{3} ) ^{2}} \frac{d}{d x} (x (ln (x))^{3})

= - \frac{1}{( x ( ln ( x ) ) ^{3} ) ^{2}} \frac{d}{d x} (x (ln (x))^{3})

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

= - \frac{1}{( x ( ln ( x ) ) ^{3} ) ^{2}} (ln^{3} (x) + 3 ln^{2} (x))

Vereinfache

- \frac{1}{( x ln ^{3} ( x ) ) ^{2}} (ln^{3} (x) + 3 ln^{2} (x)) : - \frac{ln ( x ) + 3}{x ^{2} ln ^{4} ( x )}

= - \frac{ln ( x ) + 3}{x ^{2} ln ^{4} ( x )}
