\(\left( { - 17} \right).\left( { - 19} \right)\) với \(\left( { - 25} \right).\left( { - 12} \right)\)
Ta có:\(\left( { - 17} \right).\left( { - 19} \right) = \,\,323\); \(\left( { - 25} \right).\left( { - 12} \right)\,\, = \,\,300\)
Vì \(323\,\,\, > \,\,\,300\)nên\(\left( { - 17} \right).\left( { - 19} \right)\)\(\,\,\, > \,\,\,\)\(\left( { - 25} \right).\left( { - 12} \right)\)
