integral from 2 to 4 of 4^{3x}

\int_{2}^{4} 4^{3 x} d x

\frac{2795520}{ln ( 2 )}

Decimal

4033082.84070 \dots

Solution steps

\int_{2}^{4} 4^{3 x} d x

Simplify

4^{3 x} : 6 4^{x}

= \int_{2}^{4} 6 4^{x} d x

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

= [\frac{6 4 ^{x}}{ln ( 64 )}]_{2}^{4}

\frac{6 4 ^{x}}{ln ( 64 )} = \frac{2 ^{6 x - 1}}{3 ln ( 2 )}

= [\frac{2 ^{6 x - 1}}{3 ln ( 2 )}]_{2}^{4}

Compute the boundaries:

\frac{2795520}{ln ( 2 )}

= \frac{2795520}{ln ( 2 )}

\int_{0}^{1} x 75 x^{2} + 25 d x

\int_{0}^{1} \frac{e ^{z} + 5}{e ^{z} + 5 z} d z

\int_{0}^{\infty} k e^{- 2 x} d x

\int_{0}^{2} x (x^{2} + 1)^{7} d x

\int_{0}^{π} 2 x cos (x) d x
