(6-1) * (6+1) * (6²+1) * (6⁴+1) * (6⁸+1) - 6¹⁶ + 50 = 5 * 7 (36+1) * (6⁴ +1) * (6⁸+1) - 6¹⁶ + 50 = 5*7*37 (6⁴ +1) * (6⁸+1) - 6¹⁶ + 50 = 1295 (6⁴ +1) * (6⁸+1) - 6¹⁶ + 50 = (1295*6⁴ +1295) * (6⁸+1) - 6¹⁶ + 50 = 1295 * 6¹² + 1295 * 6⁴ + 1295 * 6⁸ + 1295 - 6¹⁶ + 50 = 1295 * 6¹² + 1295 * 1296 + 1295 * 6⁸ + 1345 - 6¹⁶ = 1295 * 6¹² + 1678320 + 1295 * 6⁸ + 1345 - 6¹⁶ = 1295 * 6¹² + 1679665 + 1295 * 6⁸ - 6¹⁶
1)
2 * ( 3х + 1 ) - 5 * ( Х + 1 ) = 2
6х + 2 - 5х - 5 = 2
Х = 2 + 3
Х = 5
2)
20х - 4 * ( 2х - 1 ) + 5 * ( 1 - 2х ) = - 3
20х - 8х + 4 + 5 - 10х = - 3
2х = - 3 - 9
2х = - 12
Х = - 6
Ответ: 10*(-1)^57*137*(-1)^94=10*137*(-1)*1=-1370. Всё просто.
