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

Lösung

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

5 (2 x + 1)

Schritte zur Lösung

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

Vereinfache

\frac{5 x ^{3} + 5 x ^{2}}{x} : 5 x (x + 1)

= \frac{d}{d x} (5 x (x + 1))

Entferne die Konstante:

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

= 5 \frac{d}{d x} (x (x + 1))

Wende die Produktregel an:

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

f = x, g = x + 1

= 5 (\frac{d x}{d x} (x + 1) + \frac{d}{d x} (x + 1) x)

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

\frac{d}{d x} (x + 1) = 1

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

Vereinfache

5 (1 \cdot (x + 1) + 1 \cdot x) : 5 (2 x + 1)

= 5 (2 x + 1)
