How long will it take to do 64 rings. It is good to have a guess before working this out using the formula.
So 64 rings would take m= 264-1
You need to do this on a calculator.
264 is a very large number. It is so large it is given on my calculator as 1.844674407371 e19
That is a 20 digit number. We dont have to be able to see this number in its entirety.
The priests can do one move a second, that is 3600 moves an hour.
So we divide this number by 3600 to get the numbers of hours it would take.
The calculator will display this:
Then divide the result by 24 to see how many days it would take.
Then by 365 to find out how many years it would take (we don’t need to worry about leap years here).
Which is longer than the known age of the universe (approx 13,000,000,000)
So we have plenty of time left.
This is an example of exponential growth. With exponential growth numbers can get very big very fast.
