integral of 6a^{3x}

\int 6 a^{3 x} d x

\frac{2 a ^{3 x}}{ln ( a )} + C

Solution steps

\int 6 a^{3 x} d x

Take the constant out:

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

= 6 \cdot \int a^{3 x} d x

Apply u-substitution

: \int a^{u} \frac{1}{3} d u

= 6 \cdot \int a^{u} \frac{1}{3} d u

Take the constant out:

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

= 6 \cdot \frac{1}{3} \cdot \int a^{u} d u

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

= 6 \cdot \frac{1}{3} \cdot \frac{a ^{u}}{ln ( a )}

Substitute back

u = 3 x

= 6 \cdot \frac{1}{3} \cdot \frac{a ^{3 x}}{ln ( a )}

Simplify

6 \cdot \frac{1}{3} \cdot \frac{a ^{3 x}}{ln ( a )} : \frac{2 a ^{3 x}}{ln ( a )}

= \frac{2 a ^{3 x}}{ln ( a )}

Add a constant to the solution

= \frac{2 a ^{3 x}}{ln ( a )} + C

\int \frac{2}{x} + \frac{3}{x ^{2}} d x

\int sech (x) tanh (x) d x

\int \frac{8 + x}{x} d x

\int \frac{x ^{2} - 2 x + 3}{x ^{2} + 4 x + 8} d x

\int \frac{x ^{5}}{x ^{6} - 8} d x
