8 a^{2} x (a^{2} x^{2} + b^{2} y^{2})^{3}

Schritte zur Lösung

\frac{\partial}{\partial x} ((a^{2} x^{2} + b^{2} y^{2})^{4})

Behandle

a, b, y

als Konstanten

Wende die Kettenregel an:

4 (a^{2} x^{2} + b^{2} y^{2})^{3} \frac{\partial}{\partial x} (a^{2} x^{2} + b^{2} y^{2})

= 4 (a^{2} x^{2} + b^{2} y^{2})^{3} \frac{\partial}{\partial x} (a^{2} x^{2} + b^{2} y^{2})

\frac{\partial}{\partial x} (a^{2} x^{2} + b^{2} y^{2}) = 2 a^{2} x

= 4 (a^{2} x^{2} + b^{2} y^{2})^{3} \cdot 2 a^{2} x

Vereinfache

= 8 a^{2} x (a^{2} x^{2} + b^{2} y^{2})^{3}
