\frac{2 x - 3}{x ^{2} x ^{13}} : \frac{2}{x ^{14}} - \frac{3}{x ^{15}}

= \frac{1}{6} \cdot \int \frac{2}{x ^{14}} - \frac{3}{x ^{15}} 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

= \frac{1}{6} (\int \frac{2}{x ^{14}} d x - \int \frac{3}{x ^{15}} d x)

\int \frac{2}{x ^{14}} d x = - \frac{2}{13 x ^{13}}

\int \frac{3}{x ^{15}} d x = - \frac{3}{14 x ^{14}}

= \frac{1}{6} (- \frac{2}{13 x ^{13}} - (- \frac{3}{14 x ^{14}}))

Vereinfache

= \frac{1}{6} (- \frac{2}{13 x ^{13}} + \frac{3}{14 x ^{14}})
