45

Schritte zur Lösung

\int_{1}^{e^{3}} \frac{10 ln ( x )}{x} d x

Entferne die Konstante:

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

= 10 \cdot \int_{1}^{e^{3}} \frac{ln ( x )}{x} d x

Wende U-Substitution an

= 10 \cdot \int_{0}^{3} u d u

Wende die Potenzregel an

= 10 [\frac{u ^{2}}{2}]_{0}^{3}

Berechne die Grenzen:

\frac{9}{2}

= 10 \cdot \frac{9}{2}
