Ответ:
- \(2\cdot1,73\cdot2,01=6,9546\).
- \(3\cdot1,27\cdot3,05=11,6205\).
- \(2\cdot1,73\cdot2,01+4,4=11,3546\).
- \(3\cdot1,27\cdot3,05+5,09=16,7105\).
- \((5,18-4,82)(5,18+4,82)=0,36\cdot10=3,6\).
- \((7,17-2,83)(7,17+2,83)=4,34\cdot10=43,4\).
- \(6,4-(5,18-4,82)(5,18+4,82)=6,4-3,6=2,8\).
- \(53,4-(7,17-2,83)(7,17+2,83)=53,4-43,4=10\).
