integral from 0 to 1 of 3^{3x}

\int_{0}^{1} 3^{3 x} d x

\frac{26}{3 ln ( 3 )}

Decimal

7.88873 \dots

Solution steps

\int_{0}^{1} 3^{3 x} d x

Simplify

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

= \int_{0}^{1} 2 7^{x} d x

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

= [\frac{2 7 ^{x}}{ln ( 27 )}]_{0}^{1}

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

= [\frac{3 ^{3 x - 1}}{ln ( 3 )}]_{0}^{1}

Compute the boundaries:

\frac{26}{3 ln ( 3 )}

= \frac{26}{3 ln ( 3 )}
