integral of 3^{x+2}

integral

3^{x + 2}

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

Solution steps

\int 3^{x + 2} d x

Simplify

3^{x + 2} : 3^{x} \cdot 3^{2}

= \int 3^{x} \cdot 3^{2} d x

Take the constant out:

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

= 3^{2} \cdot \int 3^{x} d x

Simplify

= 9 \cdot \int 3^{x} d x

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

= 9 \cdot \frac{3 ^{x}}{ln ( 3 )}

Simplify

9 \cdot \frac{3 ^{x}}{ln ( 3 )} : \frac{3 ^{x + 2}}{ln ( 3 )}

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

Add a constant to the solution

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

\frac{1}{( a ^{2} + x ^{2} ) ^{0.5}}

\frac{sin ^{2} ( x )}{( 1 + sin ( x ) )}

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

\frac{2}{x ^{\frac{1}{3}}}

\frac{1}{( t t ^{2} - 1 )}
