diff = 10 × log10(P2 / P1)

diff = 10 × log10(p22 / p12)

diff = 20 × log10(p2 / p1)  because log10(a2) = 2 × log10(a) ${diff} = 10 \cdot log_{10}\left(\frac{P_2}{P_1}\right )$ ${diff} = 10 \cdot log_{10}\left(\frac{p_2^2}{p_1^2}\right )$ ${diff} = 20 \cdot log_{10}\left(\frac{p_2}{p_1}\right )$ because $log_{10}(a^2) = 2 \cdot log_{10}(a)$


some text that is not formated $a^2$ $\sqrt{5}$ $\sum_{n=0}^\infty \frac{a^n}{n!}$ $\lim_{x\to\infty}f(x)=0$ $x = a_0 + \frac{1}{a_1 + \frac{1}{a_2 + \frac{1}{a_3 + a_4}}}$

Does things work after update someone wonders... Hope the upgrade works! $a^7$ $\sqrt{7}$ test testing plugin
