Schritte zur Lösung

\int_{1}^{e^{7}} \frac{4 ln ( x )}{x} d x

Entferne die Konstante:

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

= 4 \cdot \int_{1}^{e^{7}} \frac{ln ( x )}{x} d x

Wende U-Substitution an

= 4 \cdot \int_{0}^{7} u d u

Wende die Potenzregel an

= 4 [\frac{u ^{2}}{2}]_{0}^{7}

Berechne die Grenzen:

\frac{49}{2}

= 4 \cdot \frac{49}{2}
