16. Найди значение каждого выражения. 13⋅0+7⋅9= 12:6·4·8= 81:9:3·7 = 14:7⋅5⋅9:30= 14⋅1:7⋅6:4= 56:7:8⋅5⋅4=

Выполним вычисления по действиям:

1. 13 ⋅ 0 + 7 ⋅ 9 = 0 + 63 = 63
2. 12 : 6 ⋅ 4 ⋅ 8 = 2 ⋅ 4 ⋅ 8 = 8 ⋅ 8 = 64
3. 81 : 9 : 3 ⋅ 7 = 9 : 3 ⋅ 7 = 3 ⋅ 7 = 21
4. 14 : 7 ⋅ 5 ⋅ 9 : 30 = 2 ⋅ 5 ⋅ 9 : 30 = 10 ⋅ 9 : 30 = 90 : 30 = 3
5. 14 ⋅ 1 : 7 ⋅ 6 : 4 = 14 : 7 ⋅ 6 : 4 = 2 ⋅ 6 : 4 = 12 : 4 = 3
6. 56 : 7 : 8 ⋅ 5 ⋅ 4 = 8 : 8 ⋅ 5 ⋅ 4 = 1 ⋅ 5 ⋅ 4 = 5 ⋅ 4 = 20
