Составь программу действий и вычисли: a) (92 578 + 3206) ⋅ 800 – (50 010 – 3215) ⋅ 90 б) (42 071 – 970 ⋅ 40) ⋅ 7000 – 48 000 : 80 + 256 740 ⋅ 600

a) (92 578 + 3206) ⋅ 800 – (50 010 – 3215) ⋅ 90 =

= 95 784 ⋅ 800 – 46 795 ⋅ 90 = 76 627 200 – 4 211 550 = 72 415 650

б) (42 071 – 970 ⋅ 40) ⋅ 7000 – 48 000 : 80 + 256 740 ⋅ 600 =

= (42 071 – 38 800) ⋅ 7000 – 600 + 154 044 000 = 3271 ⋅ 7000 – 600 + 154 044 000 = 22 897 000 – 600 + 154 044 000 = 176 940 400

Ответ: а) 72 415 650, б) 176 940 400
