Ответ:

  1. \(197 \cdot 5 = 985\).
  2. \(216 \cdot 4 = 864\).
  3. \(307 \cdot 3 - 704 : 8 = 921 - 88 = 833\).
  4. \(65 \cdot 8 - 535 : 5 = 520 - 107 = 413\).
  5. \(684 : 9 + (506 - 102 \cdot 3) = 76 + (506 - 306) = 276\).
  6. \(736 : 4 + (607 - 428 : 4) = 184 + (607 - 107) = 684\).

Ответ: 985; 864; 833; 413; 276; 684.
