$$\int\limits_{0}^{1} \frac{39}{\sqrt{x}}\, dx$$

Integral(39/sqrt(x), (x, 0, 1))

Detail solution

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

$\int \frac{39}{\sqrt{x}}\, dx = 39 \int \frac{1}{\sqrt{x}}\, dx$
1. Let $u = \sqrt{x}$ .
  
  Then let $du = \frac{dx}{2 \sqrt{x}}$ and substitute $2 du$ :
  
  $\int 2\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\text{False}$
    1. The integral of a constant is the constant times the variable of integration:
      
      $\int 1\, du = u$
    So, the result is: $2 u$
  Now substitute $u$ back in:
  
  $2 \sqrt{x}$
So, the result is: $78 \sqrt{x}$
Add the constant of integration:

$78 \sqrt{x}+ \mathrm{constant}$

The answer is:

$78 \sqrt{x}+ \mathrm{constant}$
