Schritte zur Lösung

\int_{0}^{10} - 6.4 \cdot 0. 9^{x} d x

Entferne die Konstante:

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

= - 6.4 \cdot \int_{0}^{10} 0. 9^{x} d x

\int a^{x} d x = \frac{a ^{x}}{ln a}

= - 6.4 [\frac{0. 9 ^{x}}{ln ( 0.9 )}]_{0}^{10}

\frac{0. 9 ^{x}}{ln ( 0.9 )} = - 9.49122 \dots \cdot 0. 9^{x}

= - 6.4 [- 9.49122 \dots \cdot 0. 9^{x}]_{0}^{10}
