integral from 1 to 2 of 4^{2x}

解

\int_{1}^{2} 4^{2 x} d x

解

\frac{60}{ln ( 2 )}

+1

十進法表記

解答ステップ

\int_{1}^{2} 4^{2 x} d x

簡素化

4^{2 x} : 1 6^{x}

= \int_{1}^{2} 1 6^{x} d x

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

= [\frac{1 6 ^{x}}{ln ( 16 )}]_{1}^{2}

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

= [\frac{2 ^{4 x - 2}}{ln ( 2 )}]_{1}^{2}

限度を計算する:

\frac{60}{ln ( 2 )}

= \frac{60}{ln ( 2 )}
