若m+2＞3.-1/3m＜5,化简|m+2|-|1-m|+|m|得（）.

已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 化简：2{（m-1)m+m(m+1)}{(m-1)m-m(m+1)}.若m是任意整数. 化简2[（m-1)m+m(m+1)]乘【(m-1)m-m(m+1)) 化简|6-m|-|2m+1|+|m+5| (m (1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m) 3(m+1)平方-5(m+1)(m-1)+2m(m-1)化简,求值 化简：(m-1)+2(m²-3m)-(2-m+5m²) 化简：|m|+|m-1|+|m-2|． 若m合适根号(3m+1)(2-m)=根号(3m+1)乘根号(2-m),化简|m-4|+|3m+1|+|m-2|. 化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3) 已知m>4,化简:|m-4|+|7-2m|+|m^2-2m+1|-|m^2-2m-3| 若m*m-3m+1=0,求分式2m*m+2\m*m的值,
