Используем результаты предыдущей задачи:
3 × 37 = 111
7 × 11 × 13 = 1001
11 × 101 = 1111
а) 101 ⋅ 3 ⋅ 37 = 101 ⋅ 111 = 11211
б) 7 ⋅ 13 ⋅ 11 ⋅ 101 = 1001 ⋅ 101 = 101101
в) 3 ⋅ 7 ⋅ 11 ⋅ 13 ⋅ 37 = 1001 ⋅ 3 ⋅ 37 = 1001 ⋅ 111 = 111111
г) 3 ⋅ 37 ⋅ 11 ⋅ 101 = 111 ⋅ 1111 = 123321
Ответ: a) 11211; б) 101101; в) 111111; г) 123321.
