integral from 2 to 5 of 2^{3x}

\int_{2}^{5} 2^{3 x} d x

\frac{32704}{3 ln ( 2 )}

Decimal

15727.29953 \dots

Solution steps

\int_{2}^{5} 2^{3 x} d x

Simplify

2^{3 x} : 8^{x}

= \int_{2}^{5} 8^{x} d x

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

= [\frac{8 ^{x}}{ln ( 8 )}]_{2}^{5}

Simplify

ln (8) : 3 ln (2)

= [\frac{8 ^{x}}{3 ln ( 2 )}]_{2}^{5}

Compute the boundaries:

\frac{32704}{3 ln ( 2 )}

= \frac{32704}{3 ln ( 2 )}
