Ответ:
- \((0.6739+1.4261)\cdot557.55:(16.7\cdot2.9-42.13)=2.1\cdot557.55:(48.43-42.13)=1170.855:6.3=185.85\).
- \((1.3892+0.8108)\cdot537.84:(15.8\cdot3.6-52.48)=2.2\cdot537.84:(56.88-52.48)=1183.248:4.4=268.92\).
- \(801.4-(74-525.35:7.9)\cdot(64.4-6.88:8.6)=801.4-(74-66.5)\cdot(64.4-0.8)=801.4-7.5\cdot63.6=801.4-477=324.4\).
- \(702.3-(59-389.64:6.8)\cdot(59.3-5.64:9.4)=702.3-(59-57.3)\cdot(59.3-0.6)=702.3-1.7\cdot58.7=702.3-99.79=602.51\).
Ответ: 1) 185,85; 2) 268,92; 3) 324,4; 4) 602,51.
