Vereinfache

4 ln (x y) + 3 ln (yz) + ln (x z) : ln (x^{5} y^{7} z^{4})

= \frac{\partial}{\partial x} (ln (x^{5} y^{7} z^{4}))

Wende die Kettenregel an:

\frac{1}{x ^{5} y ^{7} z ^{4}} \frac{\partial}{\partial x} (x^{5} y^{7} z^{4})

= \frac{1}{x ^{5} y ^{7} z ^{4}} \frac{\partial}{\partial x} (x^{5} y^{7} z^{4})

\frac{\partial}{\partial x} (x^{5} y^{7} z^{4}) = 5 y^{7} z^{4} x^{4}

= \frac{1}{x ^{5} y ^{7} z ^{4}} \cdot 5 y^{7} z^{4} x^{4}

Vereinfache

\frac{1}{x ^{5} y ^{7} z ^{4}} \cdot 5 y^{7} z^{4} x^{4} : \frac{5}{x}

= \frac{5}{x}
