The Power of the Powers! Rice on a chessboard.
Aquests dies a 1r d’ESO estem experimentant el poder de les potències. Hem estat intentant calcular el nombre de grans d’arròs que hi cabria en un tauler d’escacs si anem duplicant el nombre a cada casella.
As the story goes, when chess was presented to a great king, the king offered the inventor any reward that he wanted. The inventor asked that a single grain of rice be placed on the first square of the chessboard. Then two grains on the second square, four grains on the third, and so on. Doubling each time.
Was the king able to pay the reward?
