3. Выполните вычисления: 3 x (14: 2)= 42 : 6 x 5= 8 x (48: 8)=

Решение:

1. \( 3 \times (14 : 2) = 3 \times 7 = 21 \)
2. \( 42 : 6 \times 5 = 7 \times 5 = 35 \)
3. \( 8 \times (48 : 8) = 8 \times 6 = 48 \)
4. \( 0 \times 4 = 0 \)
5. \( 0 : 1 = 0 \)
6. \( 5 \times 1 = 5 \)
7. \( 56 : 7 = 8 \)
8. \( 7 \times 6 = 42 \)
9. \( 8 \times 9 = 72 \)

Ответ: 21, 35, 48, 0, 0, 5, 8, 42, 72.
