+130516 5^(x+1)=2(3^(2x) this is equivalent to
5*5^x = 2(3^2)^x =
5*5^x = 2*9^x
This is probably best done graphically....{I can already see that the solution lies between x= 1 and x = 2}
Here's the graph ..........https://www.desmos.com/calculator/qrwslp9g9j
The solution is about (1.559, 61.46).......
