Question 697486
First of all, please try to post your questions in an appropriate category. You will get a quicker response if you do so. This problem has nothing to do with quadratic equations. I have changed it to an appropriate category.<br>
{{{log((a))+log((b))-log((c^(1/2)))}}}
Your work is all good so far. And you may actually be finished. It depends on the exact meaning of "expand". For many teachers they want you to make the arguments as simple as possible. If this is the case then you need to use one more rule, {{{log(q, (x^y)) = y*log(q, (x))}}}, to move the exponent of the "c" out in front:
{{{log((a))+log((b))-(1/2)log((c))}}}
