In a certain culture of bacteria, the rate of increase is proportional to the number present. (a) If it is found that the number doubles in 6 hrs, how many may be expected at the end of 18 hrs? (b) If there are 10^2 at the end of 4 hrs, and 8x10^2 at the end of 8 hrs, how many were there in the beginning?
