Question

(70+20)*3 7*(60+30) (50+20)*9 4 *(40+50) (20+70) *6 9*(10+70)

Answer 1

Ответ:

(70+20)*3 = 90*3 = 270

7*(60+30) = 7*90 = 630

(50+20)*9 = 70*9 = 630

4*(40+50) = 4*90 = 360

(20+70)*6 = 90*6 = 540

9*(10+70) = 9*80 = 720

Answer 2

Let's solve these arithmetic expressions one by one:

1. (70+20)*3 = (90)*3 = 270

2. 7*(60+30) = 7*(90) = 630

3. (50+20)*9 = (70)*9 = 630

4. 4*(40+50) = 4*(90) = 360

5. (20+70)*6 = (90)*6 = 540

6. 9*(10+70) = 9*(80) = 720

So, the results are:

1. (70+20)*3 = 270
2. 7*(60+30) = 630
3. (50+20)*9 = 630
4. 4*(40+50) = 360
5. (20+70)*6 = 540
6. 9*(10+70) = 720
