Решение:

13 + 0 + 7 ⋅ 9 = 13 + 0 + 63 = 76

14 : 7 ⋅ 5 ⋅ 9 : 30 = 2 ⋅ 5 ⋅ 9 : 30 = 10 ⋅ 9 : 30 = 90 : 30 = 3

12 : 6 ⋅ 4 ⋅ 8 = 2 ⋅ 4 ⋅ 8 = 8 ⋅ 8 = 64

14 ⋅ 1 : 7 ⋅ 6 : 4 = 14 : 7 ⋅ 6 : 4 = 2 ⋅ 6 : 4 = 12 : 4 = 3

81 : 9 ⋅ 3 ⋅ 7 = 9 ⋅ 3 ⋅ 7 = 27 ⋅ 7 = 189

56 : 7 ⋅ 8 ⋅ 5 ⋅ 4 = 8 ⋅ 8 ⋅ 5 ⋅ 4 = 64 ⋅ 5 ⋅ 4 = 320 ⋅ 4 = 1280

Ответ: 76; 3; 64; 3; 189; 1280.
