integral of 2(5^x)

\int 2 (5^{x}) d x

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

Solution steps

\int 2 \cdot 5^{x} d x

Take the constant out:

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

= 2 \cdot \int 5^{x} d x

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

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

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

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

Add a constant to the solution

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

\int \frac{6}{1 + 2 x} d x

\int x (x - 2)^{5} d x

\int \frac{( 3 + x + x )}{x} d x

\int x (x + 9)^{5} d x

\int \frac{1}{x ( 2 x - 1 )} d x
