x=6/5
Explanation:
We have:
25^(2x) = 125^(3x-2)
Taking logarithms we have:
log(25^(2x)) = log(125^(3x-2))
We will use some properties of logarithms we have:
log (a^b) = bloga
Applying we get:
2xlog25 = (3x-2)log125
:. 2xlog5^2 = (3x-2)log5^3
:. 4xlog5 = 3(3x-2)log5
:. 4x = 3(3x-2)
:. 4x = 9x - 6
:. 5x=6
:. x=6/5
