Question 720089
<ul><li>ln(x/x-9) means {{{ln(x/x-9)}}} but I wonder if you intended {{{ln(x/(x-9))}}} which would be posted as: ln(x/(x-9)) or ln((x)/(x-9))</li><li>ln(x+9/x) means {{{ln(x+9/x)}}} but I wonder if you intended {{{ln((x+9)/x)}}} which would be posted as: ln((x+9)/x) or ln((x+9)/(x))</li></ul>Please re-post your and put parentheses around numerators and denominators so we tutors don't have to guess what the problem is.
