(\partial)/(\partial x)(-7x^2e^{6x})

Lösung

\frac{\partial}{\partial x} (- 7 x^{2} e^{6 x})

Lösung

- 7 (2 x e^{6 x} + e^{6 x} \cdot 6 x^{2})

Schritte zur Lösung

\frac{\partial}{\partial x} (- 7 x^{2} e^{6 x})

Entferne die Konstante:

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

= - 7 \frac{\partial}{\partial x} (x^{2} e^{6 x})

Wende die Produktregel an:

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

f = x^{2}, g = e^{6 x}

= - 7 (\frac{\partial}{\partial x} (x^{2}) e^{6 x} + \frac{\partial}{\partial x} (e^{6 x}) x^{2})

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

\frac{\partial}{\partial x} (e^{6 x}) = e^{6 x} \cdot 6

= - 7 (2 x e^{6 x} + e^{6 x} \cdot 6 x^{2})
