integral of 3^{4x+6}

\int 3^{4 x + 6} d x

\frac{3 ^{4 x + 6}}{4 ln ( 3 )} + C

Solution steps

\int 3^{4 x + 6} d x

Apply u-substitution

= \int 3^{u} \cdot \frac{1}{4} d u

Take the constant out:

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

= \frac{1}{4} \cdot \int 3^{u} d u

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

= \frac{1}{4} \cdot \frac{3 ^{u}}{ln ( 3 )}

Substitute back

u = 4 x + 6

= \frac{1}{4} \cdot \frac{3 ^{4 x + 6}}{ln ( 3 )}

Simplify

\frac{1}{4} \cdot \frac{3 ^{4 x + 6}}{ln ( 3 )} : \frac{3 ^{4 x + 6}}{4 ln ( 3 )}

= \frac{3 ^{4 x + 6}}{4 ln ( 3 )}

Add a constant to the solution

= \frac{3 ^{4 x + 6}}{4 ln ( 3 )} + C
