Answer:

log x - log 2 + log 20 - 2 log x

Step-by-step explanation:

We need to solve the equation:

[tex]log(\frac{x}{2}) + log(\frac{20}{x^2})[/tex]

We know that log(x/y) = log x - log y and

log(x^2) = 2logx

Solving we get:

[tex](log x - log 2) + (log20 - log x^2)\\(log x - log 2) + (log20 - 2 log x)[/tex]

The solution is:

log x - log 2 + log 20 - 2 log x
