Question 4

There is a positive real number $x$ not equal to either $\frac{1}{20}$ or $\frac{1}{2}$ such that $$
\log_{20x}(22x) = \log_{2x}(202x).
$$ The value $\log_{20x}(22x)$ can be written as $\log_{10}\left(\frac{m}{n}\right),$ where $m$ and $n$ are relatively prime positive integers. Find $m + n.$
