integral from 5 to 6 of f(4^x)4^x

Lösung

\int_{5}^{6} f (4^{x}) 4^{x} d x

\frac{3932160 f}{ln ( 2 )}

Schritte zur Lösung

\int_{5}^{6} f \cdot 4^{x} \cdot 4^{x} d x

Entferne die Konstante:

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

= f \cdot \int_{5}^{6} 4^{x} \cdot 4^{x} d x

Vereinfache

4^{x} \cdot 4^{x} : 1 6^{x}

= f \cdot \int_{5}^{6} 1 6^{x} d x

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

= f [\frac{1 6 ^{x}}{ln ( 16 )}]_{5}^{6}

\frac{1 6 ^{x}}{ln ( 16 )} = \frac{2 ^{4 x - 2}}{ln ( 2 )}

= f [\frac{2 ^{4 x - 2}}{ln ( 2 )}]_{5}^{6}

Berechne die Grenzen:
