21

Пошаговое объяснение:

(9х6+2):8+(4х5х3):3-(21+21):7=21

1) 9*6=54

2) 54+2=56

3) 4*5=20

4) 20*3=60

5) 21+21=42

6) 56:8=7

7) 60:3=20

8) 42:7=6

9) 7+20=27

10) 27-6=21

Answer 2

Let's break down the expression step by step:

Step 1: Calculate the multiplication and addition/subtraction within parentheses:

9 × 6 = 54 4 × 5 × 3 = 60 21 + 21 = 42

The expression becomes:

(54 + 2) : 8 + (60 : 3) - (42 : 7)

Step 2: Perform the division operations:

(54 + 2) : 8 = 56 : 8 = 7 (60 : 3) = 20 (42 : 7) = 6

The expression becomes:

7 + 20 - 6

Step 3: Perform the addition and subtraction:

7 + 20 = 27 27 - 6 = 21

Therefore, the final result of the expression (9 × 6 + 2) : 8 + (4 × 5 × 3) : 3 - (21 + 21) : 7 is 21.
