Answer 3

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

1. Start with the multiplication and division operations inside parentheses: 7740 : 86 = 90 2000 : 8 = 250 5760 : 90 = 64

   The expression becomes: 90 · 35 + 250 - 64 · 52 + 38,430 : 7

2. Perform the multiplication and division operations from left to right: 90 · 35 = 3,150 64 · 52 = 3,328

   The expression becomes: 3,150 + 250 - 3,328 + 38,430 : 7

3. Now, perform the remaining division operation: 38,430 : 7 ≈ 5,490

   The expression becomes: 3,150 + 250 - 3,328 + 5,490

4. Finally, perform the addition and subtraction operations from left to right: 3,150 + 250 = 3,400 3,400 - 3,328 = 72 72 + 5,490 = 5,562

Therefore, the value of the expression is 5,562.
