The equation `3^(2x-1)=5^(x)` has to be solved for x.
`3^(2x-1)=5^(x)`
take the log of both the side
`log(3^(2x - 1)) = log(5^x)`
Use the property of logarithm log a^b = b*log a
=> `(2x - 1)(log 3) = x*log 5`
=> `x*2*log 3 - log 3 = x*log 5`
=> `x(2*log 3 - log 5) = log 3`
=> `x = (log 3)/(2*log 3 - log 5)`
=> `x = (log 3)/(log(9/5))`
=> `x~~1.869`
The solution of the equation is approximately x = 1.869
