Answer 2

Ответ:

1)84*10=840

840-40=800

2)78*10=780

780-700=80

3)920-20=900

900*10=9000

4)720-700=20

20*8=160

5)184*100=18400

18400-300=18100

6)100*391=39100

3900-3000=900

Answer 3

Let's solve the given expressions step by step:

1. 84 * 10 - 40 = 840 - 40 = 800

2. 78 * 10 - 700 = 780 - 700 = 80

3. 10 * (920 - 20) = 10 * 900 = 9000

4. 8 * (720 - 700) = 8 * 20 = 160

5. 184 * 100 - 300 = 18,400 - 300 = 18,100

6. 100 * 391 - 3000 = 39,100 - 3000 = 36,100

Therefore, the final values of the given expressions are:

1. 84 * 10 - 40 = 800
2. 78 * 10 - 700 = 80
3. 10 * (920 - 20) = 9000
4. 8 * (720 - 700) = 160
5. 184 * 100 - 300 = 18,100
6. 100 * 391 - 3000 = 36,100
