integral of e^xg(e^x)

\int e^{x} g (e^{x}) d x

\frac{g e ^{2 x}}{2} + C

Solution steps

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

Take the constant out:

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

= g \cdot \int e^{x} e^{x} d x

Apply exponent rule:

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

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

= g \cdot \int (ee)^{x} d x

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

= g \frac{( ee ) ^{x}}{ln ( ee )}

Simplify

g \frac{( ee ) ^{x}}{ln ( ee )} : \frac{g e ^{2 x}}{2}

= \frac{g e ^{2 x}}{2}

Add a constant to the solution

= \frac{g e ^{2 x}}{2} + C

\int 30 t^{4} e^{- t^{5}} d t

\int \frac{x ^{6} e ^{x} - 5 x ^{5}}{x ^{6}} d x

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

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

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