(3m^3-2m^2+m)-(4m^3-2m^2+3m),其中m=-1; 求答案
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+.+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)
化简求值:[(3m/(m+2)-m/(m-2)]/[(2m)/m^2-4)],其中m=2/3
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
