$$\int\limits_{0}^{1} x x^{2} e^{3}\, dx$$

Integral(x^2*E^3*x, (x, 0, 1))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int x x^{2} e^{3}\, dx = e^{3} \int x x^{2}\, dx$
1. Let $u = x^{2}$ .
  
  Then let $du = 2 x dx$ and substitute $\frac{du}{2}$ :
  
  $\int \frac{u}{4}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \frac{u}{2}\, du = \frac{\int u\, du}{2}$
    1. The integral of $u^{n}$ is $\frac{u^{n + 1}}{n + 1}$ when $n \neq -1$ :
      
      $\int u\, du = \frac{u^{2}}{2}$
    So, the result is: $\frac{u^{2}}{4}$
  Now substitute $u$ back in:
  
  $\frac{x^{4}}{4}$
So, the result is: $\frac{x^{4} e^{3}}{4}$
Add the constant of integration:

$\frac{x^{4} e^{3}}{4}+ \mathrm{constant}$

The answer is:

$\frac{x^{4} e^{3}}{4}+ \mathrm{constant}$
