Express each of the following in terms of log a and log b:
(1) 1/2 log 80 - 1/2 log 5
(2) 2 log a -log b - log c
(3) log 15 - 1/2 log a
(4) log base2 - log 3 + log 5
Without knowing what a, b, and c are, or at least what log(a) and log(b) are, I cannot imagine how you could write
"(1/2)log(80)- (1/2)log(5)" "in terms of log(a) and log(b)".
It is certainly true that (1/2)log(80)- (1/2)log(5)= (1/2)log(80/5)= (1/2)log(16)= log(4) but, again, how is that connected to a and b?
