已知m和（2m-7)(2m-5)/2m-3都是正整数,则m=

m-2m-3m+4m-5m-6m+7m.2004m=? 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 已知m和（2m-7)(2m-5)/2m-3都是正整数,则m= m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值 已知m*m+m-1=0,求m*m*m+2m*m-2005 已知m^2-5m+1=0,求m^3+1/m^3 和m-1/m的值 计算(m+3m+5m+7m+.+2009m)-(2m+4m+6m+.+2008m) 计算(m+3m+5m+7m+.+2013m)-(2m+4m+6m+.+2012m) (m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=? (m+3m+5m+7m+.+2011m)-(2m+4m+6m+.+2010m) 要说理由! 计算：m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m m*m-5m-1=0则2m*m-5m+1/m*m 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)=
