Question 48566
The number of grains of wheat that the sales is requesting can be represented as follows: 1 one the first square, 2 on the second square, 4 on the third square...and so on.

{{{1+2^1+2^2+2^3+2^4}}}+...+{{{2^62+2^63}}}
The number of grains on square n is: {{{2^((n-1))}}}
A) So the number of grains on the 24th square would be: {{{2^((24-1)) = 2^23}}} = 8,388,608

B) The total number of grains on a board with only 24 squares is: {{{2^24-1}}} = 16,777,215

C) The total number of grains required to fill a 64-square checker board would be: {{{2^64-1}}} = 18,446,744,073,709,551,615
