Answer:
Step-by-step explanation:
24
The LCM of 6 and 8 is 24. To find the least common multiple (LCM) of 6 and 8, we need to find the multiples of 6 and 8 (multiples of 6 = 6, 12, 18, 24; multiples of 8 = 8, 16, 24, 32) and choose the smallest multiple that is exactly divisible by 6 and 8, i.e., 24.
5 hours because 800/25=32
32= 2^5
25 X 1 = 25
25 X 2 = 50 AFTER FIRST HOUR
25 X 2^5 = 800 AFTER FIFTH HOUR
