Schritte zur Lösung

\int_{0}^{2} 2 x (x^{2} + 3)^{3} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{0}^{2} x (x^{2} + 3)^{3} d x

Wende U-Substitution an

= 2 \cdot \int_{3}^{7} \frac{u ^{3}}{2} d u

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \frac{1}{2} \cdot \int_{3}^{7} u^{3} d u

Wende die Potenzregel an

= 2 \cdot \frac{1}{2} [\frac{u ^{4}}{4}]_{3}^{7}

Vereinfache

2 \cdot \frac{1}{2} [\frac{u ^{4}}{4}]_{3}^{7} : [\frac{u ^{4}}{4}]_{3}^{7}

= [\frac{u ^{4}}{4}]_{3}^{7}
