Answer 1

400800-(39807-580)=361373

1)39807-580=39227

2)400800-39227=361373

46895+50786+(809139-97)=

1)809139-97=809042

2)46895+50786=97681

3)809042+97681=906723

90000-709-13200:100:6=89159

1)13200:100=132

2)132:6=22

3)90000-709=89291

4)89291-132=89159

Answer 3

Let's break down the expression step by step:

1. 400 + 800 - (3980.7 - 580) = 400 + 800 - 3400.7 + 580 (performing the subtraction inside parentheses) = 1200 - 3400.7 + 580 (adding 400 and 800) = -1600.7 + 580 (subtracting 3400.7 from 1200) = -1020.7 (subtracting 1600.7 from 580)

2. 4689.5 + 50 786 + (8091.3.9 - 97) = 4689.5 + 50 786 + 72822.7 - 97 (performing the multiplication inside parentheses) = 4689.5 + 50 786 + 72822.7 - 97 (adding 4689.5, 50786, and 72822.7) = 77 298.2 (summing all the numbers)

3. 90 000 - 709 - 13 200:100:6 = 90 000 - 709 - 220 (performing the division) = 89 291 - 220 (subtracting 709 and 220) = 89 071 (subtracting 220 from 89,291)

4. 76090.4 - 5 = 76085.4 (subtracting 5 from 76,090.4)

Considering your last statement, I'm not sure what you mean by "5балов." Could you please provide more information or clarify your question?
