Решение:
1. (838008 : 9 - 410960 : 8)
(838008 : 9 = 93112)
(410960 : 8 = 51370)
(93112 - 51370 = 41742)
2. (1482 \cdot 50 + 6700 \cdot 30)
(1482 \cdot 50 = 74100)
(6700 \cdot 30 = 201000)
(74100 + 201000 = 275100)
3. (560000 : 100 \cdot 8)
(560000 : 100 = 5600)
(5600 \cdot 8 = 44800)
4. (283040 : 10 \cdot 9)
(283040 : 10 = 28304)
(28304 \cdot 9 = 254736)
