In the same video as that noted in the question above, the Professor talks about the man who invented the game of chess requesting payment in grains of wheat. All he wanted was to have the number of grains of wheat doubled on each square of the chess board. Thus there would be 1 grain of wheat on the first square, 2 grains on the second square, 4 grains on the third square and so on. Based on this, how many grains of wheat would there be on the 10^thsquare?
