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

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

\frac{6318}{ln ( 3 )}

Decimal

5750.89143 \dots

Solution steps

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

Simplify

3^{3 x} : 2 7^{x}

= \int_{2}^{3} 2 7^{x} d x

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

= [\frac{2 7 ^{x}}{ln ( 27 )}]_{2}^{3}

\frac{2 7 ^{x}}{ln ( 27 )} = \frac{3 ^{3 x - 1}}{ln ( 3 )}

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

Compute the boundaries:

\frac{6318}{ln ( 3 )}

= \frac{6318}{ln ( 3 )}

\int_{1}^{6} (8 x^{3} - 6 x^{- 2}) d x

\int_{0}^{2 π} \frac{θ ^{3}}{3} d θ

\int_{2}^{4} - 0.0008 x e^{x^{2}} d x

\int_{0}^{2} \frac{1}{3} (x + y) d y

\int_{- \infty}^{0} \frac{x}{x ^{2} + 1} d x
