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

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

\frac{7800}{ln ( 5 )}

Decimal

4846.41248 \dots

Solution steps

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

Simplify

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

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

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

= [\frac{2 5 ^{x}}{ln ( 25 )}]_{1}^{3}

Simplify

ln (25) : 2 ln (5)

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

Compute the boundaries:

\frac{7800}{ln ( 5 )}

= \frac{7800}{ln ( 5 )}
