integral from 1 to 4 of 2^{2x}

\int_{1}^{4} 2^{2 x} d x

\frac{126}{ln ( 2 )}

Decimal

181.77957 \dots

Solution steps

\int_{1}^{4} 2^{2 x} d x

Simplify

2^{2 x} : 4^{x}

= \int_{1}^{4} 4^{x} d x

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

= [\frac{4 ^{x}}{ln ( 4 )}]_{1}^{4}

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

= [\frac{2 ^{2 x - 1}}{ln ( 2 )}]_{1}^{4}

Compute the boundaries:

\frac{126}{ln ( 2 )}

= \frac{126}{ln ( 2 )}

\int_{1}^{2} \frac{x ^{3}}{6} + \frac{1}{2 x} d x

\int_{0}^{17 π} sin (x) d x

\int_{1}^{x} 1 + t^{2} d t

\int_{0}^{8} (3 x^{2} + x + 6) d x

\int_{0}^{3} 2 t d t
