3logx=log125
logx(to the power of 3)=log125
thus,x(to the power of 3)=125
x=5

3 log x = log 125
log x³ = log 125
x³ = 125
x = 5
Explanation (example)
log 10³ = 3 log 10 = 3
log 1000 = 3
hence
log 10³ = log 1000
hence
log x³ = 3 log x

What meisam was doing is to take the antilog of both sides of the equation. To know how to do this you need to study the rules for taking logs and antilogs. Those rules should be in your book in the chapter that the question is at the end of...
