Answer 2

Ответ:

28+31+22+19=100

19+(21+17)=57

5•(12+4)=80

25•13•4=1300

4•(25+7)=128

50•27•2=2700

25•(23•4)=2300

2•(35-9)=56

Answer 3

Let's solve this step by step:

1. 28 + 31 + 22 + 19 = 28 + 31 = 59 = 59 + 22 = 81 = 81 + 19 = 100

2. 19 + (21 + 17) = 19 + 38 = 57

3. 5 * (12 + 4) = 5 * 16 = 80

4. 25 * 13 * 4 = 25 * 52 = 1300

5. 4 * (25 + 7) = 4 * 32 = 128

6. 50 * 27 * 2 = 50 * 54 = 2700

7. 25 * (23 * 4) = 25 * 92 = 2300

8. 2 * (35 - 9) = 2 * 26 = 52

So, the final result of each step is as follows:

1. 100
2. 57
3. 80
4. 1300
5. 128
6. 2700
7. 2300
8. 52

I'm not sure what "Ришение в столбик" means, but these are the solutions for the given equations.
