\frac{x ^{2} + 3 x}{x ^{2}} : 1 + \frac{1}{x ^{\frac{5}{3}}}

= \int_{1}^{35} 1 + \frac{1}{x ^{\frac{5}{3}}} 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_{1}^{35} 1 d x + \int_{1}^{35} \frac{1}{x ^{\frac{5}{3}}} d x

\int_{1}^{35} 1 d x = 35 - 1

\int_{1}^{35} \frac{1}{x ^{\frac{5}{3}}} d x = - \frac{3}{2 \cdot 5 ^{\frac{2}{9}}} + \frac{3}{2}

= 35 - 1 - \frac{3}{2 \cdot 5 ^{\frac{2}{9}}} + \frac{3}{2}
