Schritte zur Lösung

\int_{5}^{8} 3 x + 1 d x

Wende U-Substitution an

= \int_{16}^{25} \frac{u}{3} d u

Entferne die Konstante:

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

= \frac{1}{3} \cdot \int_{16}^{25} u d u

Wende die Potenzregel an

= \frac{1}{3} [\frac{2}{3} u^{\frac{3}{2}}]_{16}^{25}

Berechne die Grenzen:

\frac{122}{3}

= \frac{1}{3} \cdot \frac{122}{3}
