$$x \left(- \sqrt{13} + \sqrt{3}\right) > \frac{5}{\sqrt{3} + \sqrt{13}}$$
x*(-sqrt(13) + sqrt(3)) > 5/(sqrt(3) + sqrt(13))
Detail solution
Given the inequality:
$$x \left(- \sqrt{13} + \sqrt{3}\right) > \frac{5}{\sqrt{3} + \sqrt{13}}$$
To solve this inequality, we must first solve the corresponding equation:
$$x \left(- \sqrt{13} + \sqrt{3}\right) = \frac{5}{\sqrt{3} + \sqrt{13}}$$
Solve:
Given the linear equation:
(sqrt(3)-(sqrt(13)))*x = 5/(sqrt(3)+sqrt(13))

Expand brackets in the left part
sqrt+3-sqrt-13))*x = 5/(sqrt(3)+sqrt(13))

Expand brackets in the right part
sqrt+3-sqrt-13))*x = 5/sqrt+5/3+sqrt13)

Divide both parts of the equation by sqrt(3) - sqrt(13)
x = 5/(sqrt(3) + sqrt(13)) / (sqrt(3) - sqrt(13))

$$x_{1} = - \frac{1}{2}$$
$$x_{1} = - \frac{1}{2}$$
This roots
$$x_{1} = - \frac{1}{2}$$
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{1}$$
For example, let's take the point
$$x_{0} = x_{1} - \frac{1}{10}$$
=
$$- \frac{1}{2} + - \frac{1}{10}$$
=
$$- \frac{3}{5}$$
substitute to the expression
$$x \left(- \sqrt{13} + \sqrt{3}\right) > \frac{5}{\sqrt{3} + \sqrt{13}}$$
$$\frac{\left(-3\right) \left(- \sqrt{13} + \sqrt{3}\right)}{5} > \frac{5}{\sqrt{3} + \sqrt{13}}$$
