Вопрос:

2) 103 021 - (700 051 - 686 479) * 6 + (123 450 : 5 - 8746) = ?

Ответ:

Let's solve the problem step by step:
  1. First, we calculate the difference inside the parentheses: $$700051 - 686479 = 13572$$
  2. Next, we multiply the result by 6: $$13572 * 6 = 81432$$
  3. Then, we perform the division: $$123450 : 5 = 24690$$
  4. Now, we subtract 8746 from 24690: $$24690 - 8746 = 15944$$
  5. Next, we subtract 81432 from 103021: $$103021 - 81432 = 21589$$
  6. Finally, we add 15944 to 21589: $$21589 + 15944 = 37533$$
Therefore, the final answer is:
Answer: 37533
