Ответ:
1) \(3600 : 90 - 29 \cdot 30 + 458\)
- \(3600 : 90 = 40\), \(29 \cdot 30 = 870\).
- \(40 - 870 + 458 = -830 + 458 = -372\).
2) \((5\,675 + 17\,340) : 5 - 44 \cdot 39\)
- \(5\,675 + 17\,340 = 23\,015\).
- \(23\,015 : 5 = 4\,603\), \(44 \cdot 39 = 1\,716\).
- \(4\,603 - 1\,716 = 2\,887\).
Ответ: 1) −372; 2) 2887.
