Schritte zur Lösung

\int_{0}^{1} 3 x^{2} (1 + x^{3})^{5} d x

Entferne die Konstante:

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

= 3 \cdot \int_{0}^{1} x^{2} (1 + x^{3})^{5} d x

Wende U-Substitution an

= 3 \cdot \int_{1}^{2} \frac{u ^{5}}{3} d u

Entferne die Konstante:

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

= 3 \cdot \frac{1}{3} \cdot \int_{1}^{2} u^{5} d u

Wende die Potenzregel an

= 3 \cdot \frac{1}{3} [\frac{u ^{6}}{6}]_{1}^{2}

Vereinfache

3 \cdot \frac{1}{3} [\frac{u ^{6}}{6}]_{1}^{2} : [\frac{u ^{6}}{6}]_{1}^{2}

= [\frac{u ^{6}}{6}]_{1}^{2}
