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

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

\frac{60}{ln ( 2 )}

Decimal

86.56170 \dots

Solution steps

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

Simplify

2^{4 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}

Compute the boundaries:

\frac{60}{ln ( 2 )}

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