integral of e^x3^{2x}

\int e^{x} 3^{2 x} d x

\frac{( 9 e ) ^{x}}{ln ( 9 e )} + C

Solution steps

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

3^{2 x} = 9^{x}

= \int 9^{x} e^{x} d x

Apply exponent rule:

a^{n} \cdot b^{n} = (a \cdot b)^{n}

9^{x} e^{x} = (9 e)^{x}

= \int (9 e)^{x} d x

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

= \frac{( 9 e ) ^{x}}{ln ( 9 e )}

Add a constant to the solution

= \frac{( 9 e ) ^{x}}{ln ( 9 e )} + C

\int \frac{8 x}{x ^{2} + 16} d x

\int (5 x^{6} - 8 x^{3} + 5 x + 9) d x

\int \frac{x + 4}{x ^{2} + 5 x + 6} d x

\int \frac{4 s}{( 1 - 2 s ^{2} ) ^{2}} d s
