Question 873868
Hello I guess the questions I need help with is: {{{3^(x+2)=5^(x-1)}}} What I have tried to do is take the log of both sides which gave me
(x+2)*log3=(x-1)*log5
Expand it
x*log(3) + 2log(3) = x*log(5) - log(5)
Collect x terms
x*log(3) - x*log(5) = - log(5) - log(9)
x*(log(5) - log(3)) = log(5) + log(9) = log(45)
x = log(45)/log(5/3)
