integral from 1 to 3 of 2^{5x}

\int_{1}^{3} 2^{5 x} d x

\frac{32736}{5 ln ( 2 )}

Solution steps

\int_{1}^{3} 2^{5 x} d x

Simplify

2^{5 x} : 3 2^{x}

= \int_{1}^{3} 3 2^{x} d x

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

= [\frac{3 2 ^{x}}{ln ( 32 )}]_{1}^{3}

Simplify

ln (32) : 5 ln (2)

= [\frac{3 2 ^{x}}{5 ln ( 2 )}]_{1}^{3}

Compute the boundaries:

\frac{32736}{5 ln ( 2 )}

= \frac{32736}{5 ln ( 2 )}

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

\int_{1}^{3} 9 d x

\int_{0}^{x} e^{2 x} d x

\int_{0}^{1} 4 x d x

\int_{0}^{\frac{π}{4}} cos (2 θ) d θ
