(\partial)/(\partial x)(4+xln(xy-5))

Lösung

\frac{\partial}{\partial x} (4 + x ln (x y - 5))

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

Schritte zur Lösung

\frac{\partial}{\partial x} (4 + x ln (x y - 5))

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial x} (4) + \frac{\partial}{\partial x} (x ln (x y - 5))

\frac{\partial}{\partial x} (4) = 0

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

= 0 + ln (y x - 5) + \frac{y x}{y x - 5}

Vereinfache

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

\frac{d}{d x} (x (2 - x))
