(4 - x) x : 4 x - x^{\frac{3}{2}}

= \int_{0}^{4} 4 x - x^{\frac{3}{2}} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{4} 4 x d x - \int_{0}^{4} x^{\frac{3}{2}} d x

\int_{0}^{4} 4 x d x = \frac{64}{3}

\int_{0}^{4} x^{\frac{3}{2}} d x = \frac{64}{5}

= \frac{64}{3} - \frac{64}{5}

Vereinfache

\frac{64}{3} - \frac{64}{5} : \frac{128}{15}

= \frac{128}{15}

\int_{- 6}^{- 3} - x - 2 d x

\int_{0}^{4} (13 - x) x d x

\int_{2}^{6} (8 x^{3} - 6 x^{- 2}) d x

\int_{- 2}^{2} x^{2} + 4 d x

\int_{0}^{6} 6 d x
