Schritte zur Lösung

\int (8 x^{7} + x^{5}) 6 x^{8} + x^{6} d x

Wende U-Substitution an

= \int \frac{u}{6} d u

Entferne die Konstante:

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

= \frac{1}{6} \cdot \int u d u

Wende die Potenzregel an

= \frac{1}{6} \cdot \frac{2}{3} u^{\frac{3}{2}}

Setze in

u = 6 x^{8} + x^{6}

ein

= \frac{1}{6} \cdot \frac{2}{3} (6 x^{8} + x^{6})^{\frac{3}{2}}

Vereinfache

\frac{1}{6} \cdot \frac{2}{3} (6 x^{8} + x^{6})^{\frac{3}{2}} : \frac{1}{9} x^{9} (6 x^{2} + 1)^{\frac{3}{2}}

= \frac{1}{9} x^{9} (6 x^{2} + 1)^{\frac{3}{2}}
