integral from 1 to 3 of 3^{5x}

\int_{1}^{3} 3^{5 x} d x

\frac{14348664}{5 ln ( 3 )}

Decimal

2612143.36449 \dots

Solution steps

\int_{1}^{3} 3^{5 x} d x

Simplify

3^{5 x} : 24 3^{x}

= \int_{1}^{3} 24 3^{x} d x

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

= [\frac{24 3 ^{x}}{ln ( 243 )}]_{1}^{3}

Simplify

ln (243) : 5 ln (3)

= [\frac{24 3 ^{x}}{5 ln ( 3 )}]_{1}^{3}

Compute the boundaries:

\frac{14348664}{5 ln ( 3 )}

= \frac{14348664}{5 ln ( 3 )}

\int_{0}^{π} 1 + sin (t) cos (t) d t

\int_{- 1}^{0} - x^{2} d x

\int_{1}^{e} x d x

\int_{- 2}^{2} (- 2 x^{2} + 8) d x

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