化简 m^2-2m^3+3/2m^2-1/2m+1/16
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)]乘【(m-1)m-m(m+1))
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|
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
化简:2{(m-1)m+m(m+1)}{(m-1)m-m(m+1)}.若m是任意整数.
化简:(m-1)+2(m²-3m)-(2-m+5m²)
3(m+1)平方-5(m+1)(m-1)+2m(m-1)化简,求值
(m^3-m)/(2m+2)化简
化简:|m|+|m-1|+|m-2|.
(m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m)
