derivative of (5x^3+7x^2/x)

Lösung

\frac{d}{d x} (\frac{5 x ^{3} + 7 x ^{2}}{x})

Lösung

10 x + 7

Schritte zur Lösung

\frac{d}{d x} (\frac{5 x ^{3} + 7 x ^{2}}{x})

Vereinfache

\frac{5 x ^{3} + 7 x ^{2}}{x} : x (5 x + 7)

= \frac{d}{d x} (x (5 x + 7))

Wende die Produktregel an:

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

f = x, g = 5 x + 7

= \frac{d x}{d x} (5 x + 7) + \frac{d}{d x} (5 x + 7) x

\frac{d x}{d x} = 1

\frac{d}{d x} (5 x + 7) = 5

= 1 \cdot (5 x + 7) + 5 x

Vereinfache

= 10 x + 7
