integral of 3^x*e^x

Solution

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

Solution

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

Solution steps

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

Apply exponent rule:

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

3^{x} e^{x} = (3 e)^{x}

= \int (3 e)^{x} d x

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

= \frac{( 3 e ) ^{x}}{ln ( 3 e )}

Add a constant to the solution

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