\frac{d}{d x} ((3 x + 8) x^{2})

\frac{3 x ^{\frac{3}{2}}}{2} + 2 x (3 x + 8)

Schritte zur Lösung

\frac{d}{d x} ((3 x + 8) x^{2})

Wende die Produktregel an:

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

f = 3 x + 8, g = x^{2}

= \frac{d}{d x} (3 x + 8) x^{2} + \frac{d}{d x} (x^{2}) (3 x + 8)

\frac{d}{d x} (3 x + 8) = \frac{3}{2 x}

\frac{d}{d x} (x^{2}) = 2 x

= \frac{3}{2 x} x^{2} + 2 x (3 x + 8)

\frac{3}{2 x} x^{2} = \frac{3 x ^{\frac{3}{2}}}{2}

= \frac{3 x ^{\frac{3}{2}}}{2} + 2 x (3 x + 8)
