\int\limits_{2}^{3} \left(\frac{2}{x} + \frac{4}{x^{\frac{3}{2}}}\right)\, dx

Integral(2/x + 4/x^(3/2), (x, 2, 3))

Detail solution

Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{2}{x}\, dx = 2 \int \frac{1}{x}\, dx$
  1. The integral of $\frac{1}{x}$ is $\log{\left(x \right)}$ .
  So, the result is: $2 \log{\left(x \right)}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{4}{x^{\frac{3}{2}}}\, dx = 4 \int \frac{1}{x^{\frac{3}{2}}}\, dx$
  1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
    
    $\int \frac{1}{x^{\frac{3}{2}}}\, dx = - \frac{2}{\sqrt{x}}$
  So, the result is: $- \frac{8}{\sqrt{x}}$
The result is: $2 \log{\left(x \right)} - \frac{8}{\sqrt{x}}$
Add the constant of integration:

$2 \log{\left(x \right)} - \frac{8}{\sqrt{x}}+ \mathrm{constant}$

The answer is:

2 \log{\left(x \right)} - \frac{8}{\sqrt{x}}+ \mathrm{constant}
