EPTEXCUSE MY NOOBNESS.
Ap = Av + 10 log ( Rin / Rout )
72 = 52 + 10 log ( 50,000 / Rout )
20 + 10 log ( 50,000 / Rout )
2 log ( 50,000 / Rout)
Rout = ?
I cannot solve for Rout, someone teach me?
LOL please help with simple math

2 = log(50,000) - log(Rout) ?? 10^(2-log(50,000) = Rout? | ||

2 = log(50,000) - log(Rout) ?? 10^(2-log(50,000) = (-1)Rout? 10^(-2+log(50,000) = Rout = 500 | ||

10^2= 50000/R R= 50000/100 R= 500. | ||

20 = 10 log ( 50,000 / Rout ) log ( 50,000 / Rout ) = 2 50,000 / Rout = exp(2) rout = 50000/exp(2) | ||
