(9 - x) x : 9 x - x^{\frac{3}{2}}

= \int_{0}^{2} 9 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}^{2} 9 x d x - \int_{0}^{2} x^{\frac{3}{2}} d x

\int_{0}^{2} 9 x d x = 122

\int_{0}^{2} x^{\frac{3}{2}} d x = \frac{8 2}{5}

= 122 - \frac{8 2}{5}

\int_{1}^{8} \frac{2}{t} d t

\int_{0}^{1} b (a^{4 k - 1})

\int_{0}^{2} 2 e^{x^{2} - 3 x} d x

\int_{0}^{4} x^{2} \cdot \frac{x}{8} d x

\int_{0}^{4} 2 π x (2 x) d x
