\int_{0}^{2} \frac{5}{( 2 - x ) ^{\frac{2}{3}}} d x

Entferne die Konstante:

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

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

Wende U-Substitution an

= 5 \cdot \int_{2}^{0} - \frac{1}{u ^{\frac{2}{3}}} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= 5 (- \int_{0}^{2} - \frac{1}{u ^{\frac{2}{3}}} d u)

Entferne die Konstante:

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

= 5 (- (- \int_{0}^{2} \frac{1}{u ^{\frac{2}{3}}} d u))

Wende die Potenzregel an

= 5 (- (- [3 u^{\frac{1}{3}}]_{0}^{2}))

Vereinfache

= 5 [3 u^{\frac{1}{3}}]_{0}^{2}

Berechne die Grenzen:

3 \cdot 2^{\frac{1}{3}}

= 5 \cdot 3 \cdot 2^{\frac{1}{3}}
