Question

Расставьте скобки так, чтобы равенства стали верными. 3 + 8 x 2 - 1 = 21 5 x 16 + 14 + 6 : 2 = 153 18 : 2 + 1 + 1 = 7 6 x 5+9:3 = 28 5 × 10 +1:11 = 5 3 + 40 : 8 x 5 = 4 6:9 - 8 = 6 22 - 3 x 5 + 2 = 1​

Answer 1

Ответ:

(3 + 8) x 2 - 1 = 21

5 x(16 + 14)+ 6 : 2 = 153

18 : (2 + 1) + 1 = 7

6 x (5+9):3 = 28

5 × (10 +1):11 = 5

3 + 40 : (8 x 5) = 4

6:(9 - 8) = 6

22 - 3 x (5 + 2)= 1

Answer 2

3 + (8 * (x + 2) - 1) = 21 + (5 * (x + (16 + 14 + 6))) + (2 = 153)

18 + (2 + 1 + 1) = (7 * (6 + 5 + (9 / 3))) = 28 + (5 * 10) + (1 / 11) = (5 * (3 + (40 / (8 + x + 5)) = 4 + (6 / 9) - 8 = 6 + 22 - (3 + x + 5)) + 2 = 1
