Please answer and explain so I can understand. Than you.-ok just use the properties of logarithms. What is in the denominator is positive and what is in the denominator is negative.Here is what you do.I hope you can see whats going on.......
Use the properties of logarithms to write the expression as a sum,difference, and/or constant multiple of logarithms. (assume all variables are positive)
Ln((x^2-1)/(x^3)) The question also notes that : x>1
Please answer and explain so I can understand. Than you.

ok just use the properties of logarithms. What is in the denominator is positive and what is in the denominator is negative. That is you can write it as ln(x^2 - 1) - ln(x^3) = ln(x^2 - 1) - 3ln(x)
Here is what you do. ln(a/b) = lna - lnb
ln(a*b) = lna + lnb
ln (a^n) = n*ln(a)
I hope you can see whats going on.
