Ответ:

  1. \(7000 \cdot 100 + 6000 = 700000 + 6000 = 706000\).
  2. \(8600 \cdot 100 - 60000 = 860000 - 60000 = 800000\).
  3. \(90000 : 100 + 3000 = 900 + 3000 = 3900\).
  4. \(480000 : 1000 + 5000 = 480 + 5000 = 5480\).
  5. \(736000 : 10 - 70000 = 73600 - 70000 = 3600\).
  6. \(52000 : 100 - 500 = 520 - 500 = 20\).
