integral of (x+2)(x^2+4x+10)^{1/5}

Lösung

\int (x + 2) (x^{2} + 4 x + 10)^{\frac{1}{5}} d x

\frac{5}{12} (x^{2} + 4 x + 10)^{\frac{6}{5}} + C

Schritte zur Lösung

\int (x + 2) (x^{2} + 4 x + 10)^{\frac{1}{5}} d x

Wende U-Substitution an

= \int \frac{u ^{\frac{1}{5}}}{2} d u

Entferne die Konstante:

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

= \frac{1}{2} \cdot \int u^{\frac{1}{5}} d u

Wende die Potenzregel an

= \frac{1}{2} \cdot \frac{5}{6} u^{\frac{6}{5}}

Setze in

u = x^{2} + 4 x + 10

ein

= \frac{1}{2} \cdot \frac{5}{6} (x^{2} + 4 x + 10)^{\frac{6}{5}}

Vereinfache

\frac{1}{2} \cdot \frac{5}{6} (x^{2} + 4 x + 10)^{\frac{6}{5}} : \frac{5}{12} (x^{2} + 4 x + 10)^{\frac{6}{5}}

= \frac{5}{12} (x^{2} + 4 x + 10)^{\frac{6}{5}}
