Question 715445: I am trying to expand a natural log of a fraction. I am looking at the ln of (x^2-1 over x^4). The textbook also points out that x>1 although I don't know why that information is important to solve this. The answer I came up with was ln(x^2-1)-4lnx but webassign.net says it is wrong. I am stumped and my stupid textbook doesn't explain what I'm doing wrong. Please help.
