A = 1*(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1) надо упростить 1 (2+1) = 3 = (4-1) = (2^2 -1) (2^2 -1)(2^2+1)=(2^4-1) (2^4-1)(2^4+1)=(2^8-1) (2^8-1)(2^8+1)=(2^16-1) (2^16-1)(2^16+1)=(2^32-1) (2^32-1)(2^32+1)=(2^64-1) (2^64-1)(2^64+1)=(2^128-1) 1*(2^128-1) B = (2^128-1) - окончательный вид проверка A = 340 282 366 920 938 463 463 374 607 431 768 211 455 B= 340 282 366 920 938 463 463 374 607 431 768 211 455
