m*m-2m等于1,则2m*m-4m+2012

m*m-2m等于1,则2m*m-4m+2012 m*m-5m-1=0则2m*m-5m+1/m*m m+3m+5m+...+2011m-2m-4m-...-2010m等于多少? 如果m-m分之一等于-1,则m的平方+m等于?2m的平方+2m-1等于? (m+3m+5m+.+2009m)-(2m+4m+6m+.+2010m)等于多少请说明原因 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 1／1m＝2m／4,m等于多少? 先化简再求值m^2(m+3)+2m(m^2-1)-(m^4+m^3-m^2)/1/3m其中m等于2013 计算：（m+3m+5m+...+2009m)-(2m+4m+6m+...+2008m) (m+3m+5m+...+2009m)-(2m+4m+6m+...2008m) (m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m) (m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m) (m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)= 计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m) m-2m-3m+4m-5m-6m+7m.2004m=? (m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=? 已知m*m+m-1=0,求m*m*m+2m*m-2005 化简(m*m-2m)/(4-m*m)
