integral of x*5^x

\int x \cdot 5^{x} d x

\frac{5 ^{x} x}{ln ( 5 )} - \frac{5 ^{x}}{ln ^{2} ( 5 )} + C

Solution steps

\int x \cdot 5^{x} d x

Apply Integration By Parts

: \frac{5 ^{x} x}{ln ( 5 )} - \int \frac{5 ^{x}}{ln ( 5 )} d x

= \frac{5 ^{x} x}{ln ( 5 )} - \int \frac{5 ^{x}}{ln ( 5 )} d x

\int \frac{5 ^{x}}{ln ( 5 )} d x = \frac{5 ^{x}}{ln ^{2} ( 5 )}

= \frac{5 ^{x} x}{ln ( 5 )} - \frac{5 ^{x}}{ln ^{2} ( 5 )}

Add a constant to the solution

= \frac{5 ^{x} x}{ln ( 5 )} - \frac{5 ^{x}}{ln ^{2} ( 5 )} + C

\frac{e ^{- s}}{s - 1}

- 4 t^{2} + 15 t + 8

\int (5 x^{2} + 1)^{2} (10 x) d x

\frac{d}{d x} (\frac{x}{( x + y ) ^{2}})

\frac{d}{d x} (x^{2} + x)
