(\partial)/(\partial x)(yln(5x+y))

Lösung

\frac{\partial}{\partial x} (y ln (5 x + y))

\frac{5 y}{5 x + y}

Schritte zur Lösung

\frac{\partial}{\partial x} (y ln (5 x + y))

Behandle

y

als Konstante

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= y \frac{\partial}{\partial x} (ln (5 x + y))

Wende die Kettenregel an:

\frac{1}{5 x + y} \frac{\partial}{\partial x} (5 x + y)

= \frac{1}{5 x + y} \frac{\partial}{\partial x} (5 x + y)

\frac{\partial}{\partial x} (5 x + y) = 5

= y \frac{1}{5 x + y} \cdot 5

Vereinfache

y \frac{1}{5 x + y} \cdot 5 : \frac{5 y}{5 x + y}

= \frac{5 y}{5 x + y}
