\frac{8 y ^{\frac{5}{3}}}{3}

Schritte zur Lösung

\int_{0}^{y} \frac{32}{9} (x y)^{\frac{1}{3}} d x

Entferne die Konstante:

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

= \frac{32}{9} \cdot \int_{0}^{y} (y x)^{\frac{1}{3}} d x

(y x)^{\frac{1}{3}} = y^{\frac{1}{3}} x^{\frac{1}{3}}

= \frac{32}{9} \cdot \int_{0}^{y} y^{\frac{1}{3}} x^{\frac{1}{3}} d x

Entferne die Konstante:

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

= \frac{32}{9} y^{\frac{1}{3}} \cdot \int_{0}^{y} x^{\frac{1}{3}} d x

Wende die Potenzregel an

= \frac{32}{9} y^{\frac{1}{3}} [\frac{3}{4} x^{\frac{4}{3}}]_{0}^{y}

Berechne die Grenzen:

\frac{3}{4} y^{\frac{4}{3}}

= \frac{32}{9} y^{\frac{1}{3}} \frac{3}{4} y^{\frac{4}{3}}

Vereinfache

= \frac{8 y ^{\frac{5}{3}}}{3}

\int_{- 4}^{0} (x + 1) d x
