You can put this solution on YOUR website! In this equation we need to take logarithm on both sides:
log(5^2x-3) = log(6^3x)
then simplify it: (2x-3)log(5) = 3xlog(6)
expand the left side: 2xlog(5) - 3log(5) = 3xlog(6)
move x terms together: 2xlog(5) - 3xlog(6) = 3log(5)
combine x terms: x(2log(5) - 3log(6)) = 3log(5)
then:
or
If you need an numerical answer, it is x = -2.239
Hope this helps :)
