Question 403466: Take a penny and double it 64 times. How much do you have?
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! If you mean double and keep all the pennies, 1+2+4+8 etc, = 2^65 - 1 pennies
If you mean the amount doubled 64 times, that's 2^64 pennies
------------
2^64 pennies =~ $18,446,744,070,000,000,000.00
2^65 is about 2x that amount.
--------------
Looking again, that's the number of pennies, not dollars.
Divide by 100.
