解答ステップ

\int_{0}^{1} 4^{5 x} d x

簡素化

4^{5 x} : 102 4^{x}

= \int_{0}^{1} 102 4^{x} d x

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

= [\frac{102 4 ^{x}}{ln ( 1024 )}]_{0}^{1}

\frac{102 4 ^{x}}{ln ( 1024 )} = \frac{2 ^{10 x - 1}}{5 ln ( 2 )}

= [\frac{2 ^{10 x - 1}}{5 ln ( 2 )}]_{0}^{1}

限度を計算する:

\frac{1023}{10 ln ( 2 )}

= \frac{1023}{10 ln ( 2 )}
