Question 716612
<ul><li>What are you/we supposed to do with that expression?</li><li>Put parentheses around numerators and denominators, especially if they have multiple terms. What you posted meant:
{{{x+1/(x+7)(x-4)}}}
which I suspect is not the expression you intended.</li><li>The expression has nothing to do with logarithms. Please post questions under a relevant category.</li></ul>
