Write down the positive integers in row one, cross out every th number, and write the partial sums of the remaining numbers in the row below. Now cross off every
th number and write the partial sums of the remaining numbers in the row below. Continue. For every positive integer
, if every
th number is ignored in row 1, every
th number in row 2, and every
th number in row
, then the
th row of partial sums will be the
th powers
