उत्तर
Machine, `1/8` are `1/2, 1/2, 1/2`.
So, `1/8 = 1/2 xx 1/2 xx 1/2 = (1/2)^3`
Hence, `(xx 1/2^3)` repeater machine can do the same work as a `(xx 1/8)` machine.

Long back in ancient times, a farmer saved the life of a king’s daughter. The king decided to reward the farmer with whatever he wished. The farmer, who was a chess champion, made an unusal request:
“I would like you to place 1 rupee on the first square of my chessboard, 2 rupees on the second square, 4 on the third square, 8 on the fourth square, and so on, until you have covered all 64 squares. Each square should have twice as many rupees as the previous square.” The king thought this to be too less and asked the farmer to think of some better reward, but the farmer didn’t agree.
How much money has the farmer earned?
