Thread: Statements with ln

In the following practice example Im confused, I think the first and third are true but I am not sure Im doing it right at all. Confused.


Which of the following statements is true, or are none of them true?


ln(x-2) = ln x - ln 2
ln(x-2) = x - ln 2
ln(x-2) = ln(x/2) <- x/2 written as fraction
