There is a container with 64 liters of pure alcohol. 32 liters were poured out of the container and replaced with pure water. How many times should you repeat this operation to get a solution with only 2 liters of alcohol?

so we divide by 2 every time so 64/2^x=2 we then solve that 64=2^6 so 6-1=5 so we need to do this 5 times.
