Integral(sqrt(x)*log(x)^2, (x, 0, 1))

Detail solution

Let $u = \log{\left(x \right)}$ .

Then let $du = \frac{dx}{x}$ and substitute $du$ :

$\int u^{2} e^{\frac{3 u}{2}}\, du$
1. Use integration by parts:
  
  $\int \operatorname{u} \operatorname{dv} = \operatorname{u}\operatorname{v} - \int \operatorname{v} \operatorname{du}$
  
  Let $u{\left(u \right)} = u^{2}$ and let $\operatorname{dv}{\left(u \right)} = e^{\frac{3 u}{2}}$ .
  
  Then $\operatorname{du}{\left(u \right)} = 2 u$ .
  
  To find $v{\left(u \right)}$ :
  1. There are multiple ways to do this integral.
    Method #1
    1. Let $u = \frac{3 u}{2}$ .
      
      Then let $du = \frac{3 du}{2}$ and substitute $\frac{2 du}{3}$ :
      
      $\int \frac{4 e^{u}}{9}\, du$
      
      The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \frac{2 e^{u}}{3}\, du = \frac{2 \int e^{u}\, du}{3}$
      
      The integral of the exponential function is itself.
      
      $\int e^{u}\, du = e^{u}$
      
      So, the result is: $\frac{2 e^{u}}{3}$
      
      Now substitute $u$ back in:
      
      $\frac{2 e^{\frac{3 u}{2}}}{3}$
    Method #2
    1. Let $u = e^{\frac{3 u}{2}}$ .
      
      Then let $du = \frac{3 e^{\frac{3 u}{2}} du}{2}$ and substitute $\frac{2 du}{3}$ :
      
      $\int \frac{4}{9}\, du$
      
      The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \frac{2}{3}\, du = \frac{2 \int 1\, du}{3}$
      
      The integral of a constant is the constant times the variable of integration:
      
      $\int 1\, du = u$
      
      So, the result is: $\frac{2 u}{3}$
      
      Now substitute $u$ back in:
      
      $\frac{2 e^{\frac{3 u}{2}}}{3}$
  Now evaluate the sub-integral.
2. Use integration by parts:
  
  $\int \operatorname{u} \operatorname{dv} = \operatorname{u}\operatorname{v} - \int \operatorname{v} \operatorname{du}$
  
  Let $u{\left(u \right)} = \frac{4 u}{3}$ and let $\operatorname{dv}{\left(u \right)} = e^{\frac{3 u}{2}}$ .
  
  Then $\operatorname{du}{\left(u \right)} = \frac{4}{3}$ .
  
  To find $v{\left(u \right)}$ :
  1. Let $u = \frac{3 u}{2}$ .
    
    Then let $du = \frac{3 du}{2}$ and substitute $\frac{2 du}{3}$ :
    
    $\int \frac{4 e^{u}}{9}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \frac{2 e^{u}}{3}\, du = \frac{2 \int e^{u}\, du}{3}$
      1. The integral of the exponential function is itself.
        
        $\int e^{u}\, du = e^{u}$
      So, the result is: $\frac{2 e^{u}}{3}$
    Now substitute $u$ back in:
    
    $\frac{2 e^{\frac{3 u}{2}}}{3}$
  Now evaluate the sub-integral.
3. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{8 e^{\frac{3 u}{2}}}{9}\, du = \frac{8 \int e^{\frac{3 u}{2}}\, du}{9}$
  1. Let $u = \frac{3 u}{2}$ .
    
    Then let $du = \frac{3 du}{2}$ and substitute $\frac{2 du}{3}$ :
    
    $\int \frac{4 e^{u}}{9}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \frac{2 e^{u}}{3}\, du = \frac{2 \int e^{u}\, du}{3}$
      1. The integral of the exponential function is itself.
        
        $\int e^{u}\, du = e^{u}$
      So, the result is: $\frac{2 e^{u}}{3}$
    Now substitute $u$ back in:
    
    $\frac{2 e^{\frac{3 u}{2}}}{3}$
  So, the result is: $\frac{16 e^{\frac{3 u}{2}}}{27}$
Now substitute $u$ back in:

$\frac{2 x^{\frac{3}{2}} \log{\left(x \right)}^{2}}{3} - \frac{8 x^{\frac{3}{2}} \log{\left(x \right)}}{9} + \frac{16 x^{\frac{3}{2}}}{27}$
Now simplify:

$\frac{2 x^{\frac{3}{2}} \cdot \left(9 \log{\left(x \right)}^{2} - 12 \log{\left(x \right)} + 8\right)}{27}$
Add the constant of integration:

$\frac{2 x^{\frac{3}{2}} \cdot \left(9 \log{\left(x \right)}^{2} - 12 \log{\left(x \right)} + 8\right)}{27}+ \mathrm{constant}$

The answer is:

$\frac{2 x^{\frac{3}{2}} \cdot \left(9 \log{\left(x \right)}^{2} - 12 \log{\left(x \right)} + 8\right)}{27}+ \mathrm{constant}$
