Correct! ln ba = a ln b
ln ex + ln (x2/y) + ln (y/ex) - ln x
Applying the rules for logarithms: In the first round the first term is of the form ba, and the second and third terms are quotients (a/b).
x ln e + ln x2 - ln y + ln y - ln ex - ln x
Since ln e = 1:
x + ln x2 - ln ex - ln x
Again apply the rules:
x + 2 ln x - x ln e - ln x
x + 2 ln x - x - ln x = ln x
If you still have difficulty with these concepts you sre STRONGLY urged to use the tutorial Logarithms.
