Answer 2

Відповідь:

7 740:86 · 35+2000:8-(5 760:90) = 90 * 35 + 250 - 64 = 3150 + 250 - 64 = 3336

52+38 430: 7 = 52 + 5490 = 5542

7 740:86 · 35+2000:8-(5 760:90) · 52+38 430: 7 = 90 * 35 + 250 - 64 * 52 + 5490 = 3150 + 250 - 3328 + 5490 = 5562

Answer 3

To solve the given expression, let's break it down step by step:

1. First, let's simplify the expression inside the parentheses: (5 + 760:90). - The expression 760:90 represents the division of 760 by 90, which equals 8.4444. - Adding 5 to 8.4444 gives us 13.4444.

2. Now, let's simplify the expression inside the second set of parentheses: 35 + 2000:8. - The expression 2000:8 represents the division of 2000 by 8, which equals 250. - Adding 35 to 250 gives us 285.

3. Next, let's substitute the simplified expressions back into the original expression: 7 + 740:86 - 13.4444. - The expression 740:86 represents the division of 740 by 86, which equals 8.6047. - Subtracting 13.4444 from 8.6047 gives us -4.8397.

4. Finally, let's substitute the result back into the original expression: 52 + 38 + 430 + 7 - (-4.8397). - Subtracting a negative number is the same as adding the positive equivalent, so -(-4.8397) becomes +4.8397. - Adding all the numbers together gives us 531.8397.

Therefore, the value of the expression 7 + 740:86 · 35 2000:8 - (5 + 760:90) + 52 + 38 + 430 + 7 is approximately 531.8397.
