integral of [ 2/7 (3^x)]

\int [\frac{2}{7} (3^{x})] d x

\frac{2}{7} \cdot \frac{3 ^{x}}{ln ( 3 )} + C

Solution steps

\int \frac{2}{7} \cdot 3^{x} d x

Take the constant out:

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

= \frac{2}{7} \cdot \int 3^{x} d x

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

= \frac{2}{7} \cdot \frac{3 ^{x}}{ln ( 3 )}

Add a constant to the solution

= \frac{2}{7} \cdot \frac{3 ^{x}}{ln ( 3 )} + C

\int 2 x^{2} - 3 x + 1 d x

\int \frac{x ^{2}}{x ^{2} + 5 x - 24} d x

\int e^{- (x^{2})^{2}} d (x^{2})^{2}

\int sec (29 x) tan (29 x) d x

\int 4 x^{3} e^{- x} d x
