integral of 5^{2x-7}

integral

5^{2 x - 7}

\frac{5 ^{2 x - 7}}{2 ln ( 5 )} + C

Solution steps

\int 5^{2 x - 7} d x

Apply u-substitution

= \int 5^{u} \cdot \frac{1}{2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int 5^{u} d u

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

= \frac{1}{2} \cdot \frac{5 ^{u}}{ln ( 5 )}

Substitute back

u = 2 x - 7

= \frac{1}{2} \cdot \frac{5 ^{2 x - 7}}{ln ( 5 )}

Simplify

\frac{1}{2} \cdot \frac{5 ^{2 x - 7}}{ln ( 5 )} : \frac{5 ^{2 x - 7}}{2 ln ( 5 )}

= \frac{5 ^{2 x - 7}}{2 ln ( 5 )}

Add a constant to the solution

= \frac{5 ^{2 x - 7}}{2 ln ( 5 )} + C
