Description: Lemma for 4001prm . Calculate a power mod. In decimal, we calculate 2 ^ 1 2 = 4 0 9 6 = N + 9 5 , 2 ^ 2 4 = ( 2 ^ 1 2 ) ^ 2 == 9 5 ^ 2 = 2 N + 1 0 2 3 , 2 ^ 2 5 = 2 ^ 2 4 x. 2 == 1 0 2 3 x. 2 = 2 0 4 6 , 2 ^ 5 0 = ( 2 ^ 2 5 ) ^ 2 == 2 0 4 6 ^ 2 = 1 0 4 6 N + 1 0 7 0 , 2 ^ 1 0 0 = ( 2 ^ 5 0 ) ^ 2 == 1 0 7 0 ^ 2 = 2 8 6 N + 6 1 4 and 2 ^ 2 0 0 = ( 2 ^ 1 0 0 ) ^ 2 == 6 1 4 ^ 2 = 9 4 N + 9 0 2 == 9 0 2 .
