1. The problem statement, all variables and given/known data If Logb2=A and Logb49=B, what is logb397, in terms of A and B. This is one of the bonus question in my geometric quiz and i don't remember if the number is 397. I wonder if anyone get this? 2. Relevant equations 3. The attempt at a solution here is what i did bA=2 and bB=49 b=21/A b=491/B 491/B=21/A --> log(49)/log(2)=B/A because this is geometric quiz, so i assume this one have a geometric so i use arn-1 r : log(49)/log(2)=B/A a : log(2) log(2)(B/A)n-1=logb397 am i right?
