1. The problem statement, all variables and given/known data This problem is giving me issues, mainly because of how it is set up. 2. Relevant equations Here is a picture of what my problem is, http://img23.imageshack.us/img23/1723/heko.png [Broken] 3. The attempt at a solution I am attempting to solve this problem, and I haven't encountered anything like it in the book so far, I'm assuming I take the variables "q of x" and "r of x", but when solving, why are they swapped around? Is the (r0q)(1)= and (q0r)(1)= representing multiplication? I haven't seen that raised circle in the middle before. I'm assuming it has something to do with logarithms? I don't need anyone to show me how this particular problem is solved, [that would be cheating though it doesn't really matter to much in this class, 90% of the grade is based on the test] If someone could change the variables and numbers, and/or just go through the steps on how I should go about solving this type of problem, I would really appreciate it.
