Alright, I'm trying this problem and I am completely lost. Are there any websites to understand logs? I went to the tutorial in the helpful math sites section and after I got so far into, I was really lost.
Anyways.. here's the question. Unlike the other one, I can't figure this out.
All of these have the subscript of 2.
I tried first dividing the 6 by 15, and then multiplying the answer by 20 and ended up with 8. However, the answer in the back is 3, so I know I'm doing something wrong? I just don't get these things...
