Answer 2

а) 5:56 + 127∙556−434 5:56 = 5 + 56/100 = 5.56 5.56 + 127*556 - 434 = 5.56 + 70612 - 434 = 5.56 + 70178 = 70183.56

б) 2:223 + 145∙313−256 2:223 = 2 + 223/1000 = 2.223 2.223 + 145*313 - 256 = 2.223 + 45085 - 256 = 2.223 + 44829 = 44831.223

в) 4:445 + 227∙514−71112 4:445 = 4 + 445/1000 = 4.445 4.445 + 227*514 - 71112 = 4.445 + 116678 - 71112 = 4.445 + 45566 = 45570.445

г) 329−(48:45−13)∙2111 48:45 = 48/45 = 1.0667 329 - (1.0667 - 13) * 2111 = 329 - (-11.9333) * 2111 = 329 + 25171.5663 = 25400.5663

д) (30:27−13)∙217+25 30:27 = 30/27 = 1.1111 (1.1111 - 13) * 217 + 25 = (-11.8889) * 217 + 25 = -2576.1113 + 25 = -2551.1113

е) (48:45−13)∙2311+35 (48:45 - 13) * 2311 + 35 = (1.0667 - 13) * 2311 + 35 = (-11.9333) * 2311 + 35 = -27551.2663 + 35 = -27516.2663

ж) (33:30−45)∙229+25 (33:30 - 45) * 229 + 25 = (1.1 - 45) * 229 + 25 = (-43.9) * 229 + 25 = -10049.1 + 25 = -10024.1

з) (12−13)2:(13−14)2∙(12)3 (12 - 13)^2 / (13 - 14)^2 * (12)^3 = 1 / 1 * 1728 = 1728

и) 3:334+225∙212−356 3:334 = 3 + 334/1000 = 3.334 3.334 + 225*212 - 356 = 3.334 + 47700 - 356 = 3.334 + 47344 = 47347.334

к) (1−12)3:(13−14)2∙(32)2 (1 - 12)^3 / (13 - 14)^2 * (32)^2 = (-11)^3 / 1 * 1024 = -1331 * 1024 = -1363968

л) (712−12)∙3201324:(712+12) (712 - 12) * 3201324 / (712 + 12) = 700 * 3201324 / 724 = 2240926800 / 724 = 3096648.62

м) (14+23)∙611(34−13):59 (14 + 23) * 611 * (34 - 13) / 59 = 37 * 611 * 21 / 59 = 142167 / 59 = 2409.8136
