2m∧3-3m∧2-3m+14=0
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
2m∧3-3m∧2-3m+14=0
若m*m-3m+1=0,求分式2m*m+2\m*m的值,
(m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)
当m= 时,2m(3m-5)+3m(1-2m)=14
