Question 292093
Solve the equation, log9 (b + 4) - log9 (b - 3) = log9 8. 
I tried to figure out a couple of ways; and came up with the answer that b=4.
Is this answer correct? 
--------------
Sub 4, see if it's correct:
Since the base is consistent,
log(8) - log(1) = log(8)
log(1) = 0 for any base, so it's correct.
