1. The problem statement, all variables and given/known data I have been trying to solve this problem all day, I have used up 3 pages and to no avail. I don't think i should try and change the bases because of the way the book is set up changing bases is not until the next chapter. So I want to try and get it out without changing bases. Can someone give me a hint? The question is number 8 2. Relevant equations 3. The attempt at a solution My work is 3 pages of scratch work so it is hard to type out but all I have done is try to combine the logs shown into 2 separate logs for the base a and the base 10. I get stuck there since I can't remove the logs.
