als Konstanten

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = ln (x + 2 y + 3 z)

= \frac{\partial}{\partial x} (x) ln (x + 2 y + 3 z) + \frac{\partial}{\partial x} (ln (x + 2 y + 3 z)) x

\frac{\partial}{\partial x} (x) = 1

\frac{\partial}{\partial x} (ln (x + 2 y + 3 z)) = \frac{1}{x + 2 y + 3 z}

= 1 \cdot ln (x + 2 y + 3 z) + \frac{1}{x + 2 y + 3 z} x

Vereinfache

1 \cdot ln (x + 2 y + 3 z) + \frac{1}{x + 2 y + 3 z} x : ln (x + 2 y + 3 z) + \frac{x}{x + 2 y + 3 z}

= ln (x + 2 y + 3 z) + \frac{x}{x + 2 y + 3 z}
