integral from 0 to 3 of 4^{2x}

\int_{0}^{3} 4^{2 x} d x

\frac{4095}{4 ln ( 2 )}

Decimal

1476.95904 \dots

Solution steps

\int_{0}^{3} 4^{2 x} d x

Simplify

4^{2 x} : 1 6^{x}

= \int_{0}^{3} 1 6^{x} d x

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

= [\frac{1 6 ^{x}}{ln ( 16 )}]_{0}^{3}

\frac{1 6 ^{x}}{ln ( 16 )} = \frac{2 ^{4 x - 2}}{ln ( 2 )}

= [\frac{2 ^{4 x - 2}}{ln ( 2 )}]_{0}^{3}

Compute the boundaries:

\frac{4095}{4 ln ( 2 )}

= \frac{4095}{4 ln ( 2 )}

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

\int_{- 1}^{1} ∣ x ∣ cos (nπ x) d x

\int_{- 1}^{0} x^{3} (x^{2} - 1)^{10} d x

\int_{- 2}^{0} 2 x^{3} + 6 x^{2} + 4 x d x

\int_{0}^{8} (x - \frac{1}{2}) d x
