derivative of x^3ln(7x)

Lösung

\frac{d}{d x} (x^{3} ln (7 x))

Lösung

3 x^{2} ln (7 x) + x^{2}

Schritte zur Lösung

\frac{d}{d x} (x^{3} ln (7 x))

Wende die Produktregel an:

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

f = x^{3}, g = ln (7 x)

= \frac{d}{d x} (x^{3}) ln (7 x) + \frac{d}{d x} (ln (7 x)) x^{3}

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

\frac{d}{d x} (ln (7 x)) = \frac{1}{x}

= 3 x^{2} ln (7 x) + \frac{1}{x} x^{3}

\frac{1}{x} x^{3} = x^{2}

= 3 x^{2} ln (7 x) + x^{2}
