当m>6时,化简|m-1|-|5-m|+|m-6|
当m>6时,化简|m-1|-|5-m|+|m-6|
将下列不等式化成m>a或m<a的形式;m+4<67m<6m-5 3m+1/21-2m
化简|6-m|-|2m+1|+|m+5| (m
当m-n+5(m+n)时,求[6(m-n)]/(m+n)-[5(m+n)]/(m-n)
当m= 时,2m(3m-5)+3m(1-2m)=14
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
(m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
m-2m-3m+4m-5m-6m+7m.2004m=?
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
