\frac{8 x ^{\frac{1}{3}} ( - x ^{\frac{4}{3}} + 1 )}{3}

Schritte zur Lösung

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

Entferne die Konstante:

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

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

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

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

Entferne die Konstante:

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

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

Wende die Potenzregel an

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

Berechne die Grenzen:

\frac{3}{4} - \frac{3}{4} x^{\frac{4}{3}}

= \frac{32}{9} x^{\frac{1}{3}} (\frac{3}{4} - \frac{3}{4} x^{\frac{4}{3}})

Vereinfache

= \frac{8 x ^{\frac{1}{3}} ( - x ^{\frac{4}{3}} + 1 )}{3}

\int_{0}^{2} 1 + 4 x + x^{2} d x

\int_{1}^{5} e^{2 x - 1} d x

\int_{0}^{x^{2}} t^{2} e^{t^{2}} d t

\int_{0}^{4} \frac{x}{1 + x ^{2}} d x
