如果n阶行列式中等于零的元素个数大于[tex=2.429x1.357]+0qXgjwqwua10m6cp1nrQA==[/tex]，那么此行列式的值为[input=type:blank,size:6][/input].
举一反三
- 试证：[tex=0.643x0.786]SBMIs+VUk7//BOpfqlQl0w==[/tex]阶行列式中零元素的个数如果多于[tex=2.429x1.357]+0qXgjwqwua10m6cp1nrQA==[/tex]个，则此行列式 等于０．
- 如果n阶行列式中，负项的个数为偶数，则n≥[input=type:blank,size:6][/input].
- 行列式 [tex=9.571x5.929]xbOkdWXE1V4xsD8dsMow0tqfdFDWB9Bc0doKN7g6CNFlz+hqmP9HAGLs/Yw7wRBrR5vXhYtEaI3rFfEVNq6UHlb8txfjvffmg+b5uf9wdZFqkNHnjemvcT5vBEjAhuk1pohqic070V8PFDkW6Af8sGjTqP3JZOI6lWHju30pwL9TuFrSBbiw4+fNo1IAfYEcPVxSVNvVV2o11wwVs5m05DQ7x7zO0fpg6bTiSob4CXk+sYfjHCZUaZH5gWiVJp34hV7TC8Dl/WHQgcLnRyN+wWaocOhomdfXaQINoI84k/TkFsfiebGsBDv0H8sUXCyeOsGADy56xeWRf7UBocLvaVsDJ5WlzgW0Ve9BtfLHpuwRoza/vSbIVa+4FRA+q0Fe[/tex]的值为[input=type:blank,size:6][/input]
