integral of e^{ln(x)}*e^{2x}(x^{-1}+2)

\int e^{l n (x)} \cdot e^{2 x} (x^{- 1} + 2) d x

e^{2 x} x + C

Solution steps

\int e^{l n (x)} e^{2 x} (x^{- 1} + 2) d x

Simplify

e^{l n (x)} e^{2 x} (x^{- 1} + 2) : e^{2 x} + 2 e^{2 x} x

= \int e^{2 x} + 2 e^{2 x} x d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int e^{2 x} d x + \int 2 e^{2 x} x d x

\int e^{2 x} d x = \frac{1}{2} e^{2 x}

\int 2 e^{2 x} x d x = e^{2 x} x - \frac{1}{2} e^{2 x}

= \frac{1}{2} e^{2 x} + e^{2 x} x - \frac{1}{2} e^{2 x}

Simplify

\frac{1}{2} e^{2 x} + e^{2 x} x - \frac{1}{2} e^{2 x} : e^{2 x} x

= e^{2 x} x

Add a constant to the solution

= e^{2 x} x + C

\int x^{3} (x^{3} + \frac{3}{x}) d x

\int e^{- 2 x} cos (5 x) d x

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

\int \frac{3}{x ( x ^{2} + 5 ) ^{2}} d x

\int (cos^{2} (4 x) + sin^{2} (4 x)) d x
