log0,5x>1 inequation

Given the inequality:
$$\log{\left(0.5 x \right)} > 1$$
To solve this inequality, we must first solve the corresponding equation:
$$\log{\left(0.5 x \right)} = 1$$
Solve:
Given the equation
$$\log{\left(0.5 x \right)} = 1$$
$$\log{\left(0.5 x \right)} = 1$$
This equation is of the form:

log(v)=p

By definition log

v=e^p

then
$$0.5 x = e^{1^{-1}}$$
simplify
$$0.5 x = e$$
$$x = 2 e$$
$$x_{1} = 5.43656365691809$$
$$x_{1} = 5.43656365691809$$
This roots
$$x_{1} = 5.43656365691809$$
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
$$x_{0} = x_{1} - \frac{1}{10}$$
=
$$- \frac{1}{10} + 5.43656365691809$$
=
$$5.33656365691809$$
substitute to the expression
$$\log{\left(0.5 x \right)} > 1$$
$$\log{\left(0.5 \cdot 5.33656365691809 \right)} > 1$$

0.981434755330334 > 1

Then
$$x < 5.43656365691809$$
no execute
the solution of our inequality is:
$$x > 5.43656365691809$$
