integral of 4x^4e^{2x^5}

\int 4 x^{4} e^{2 x^{5}} d x

\frac{2}{5} e^{2 x^{5}} + C

Solution steps

\int 4 x^{4} e^{2 x^{5}} d x

Take the constant out:

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

= 4 \cdot \int x^{4} e^{2 x^{5}} d x

Apply u-substitution

= 4 \cdot \int \frac{e ^{2 u^{\frac{5}{4}}} u ^{\frac{1}{4}}}{4} d u

Take the constant out:

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

= 4 \cdot \frac{1}{4} \cdot \int e^{2 u^{\frac{5}{4}}} u^{\frac{1}{4}} d u

Apply u-substitution

= 4 \cdot \frac{1}{4} \cdot \int \frac{4 e ^{2 v}}{5} d v

Take the constant out:

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

= 4 \cdot \frac{1}{4} \cdot \frac{4}{5} \cdot \int e^{2 v} d v

Apply u-substitution

= 4 \cdot \frac{1}{4} \cdot \frac{4}{5} \cdot \int e^{w} \frac{1}{2} d w

Take the constant out:

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

= 4 \cdot \frac{1}{4} \cdot \frac{4}{5} \cdot \frac{1}{2} \cdot \int e^{w} d w

Use the common integral:

\int e^{w} d w = e^{w}

= 4 \cdot \frac{1}{4} \cdot \frac{4}{5} \cdot \frac{1}{2} e^{w}

Substitute back

= 4 \cdot \frac{1}{4} \cdot \frac{4}{5} \cdot \frac{1}{2} e^{2 (x^{4})^{\frac{5}{4}}}

Simplify

4 \cdot \frac{1}{4} \cdot \frac{4}{5} \cdot \frac{1}{2} e^{2 (x^{4})^{\frac{5}{4}}} : \frac{2}{5} e^{2 x^{5}}

= \frac{2}{5} e^{2 x^{5}}

Add a constant to the solution

= \frac{2}{5} e^{2 x^{5}} + C
