m=-1时,-2㎡-【-4m+(-m)】=?
当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m}
√(3m+1)(2-m)=√3m+1×√2-m成立时|m-4|√9m^2 6m+1+|m-2|化简
m*m-5m-1=0则2m*m-5m+1/m*m
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
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
先化简,再求值：当=1/2时,求15㎡-9-｛-4m²+[5m-8m²-(2m²-m)]-3m}的值
当m=1时,-2m^2-【-4m^2+(-m^2)】的值为
(m+2/m^2-2m)-(m-1)/(m^2-4m+4)除以m-1/m,其中m=4
已知m-1/m=3,m不等于0,求m^2-1/m^2,m^3-1/m^3,m^4-1/m^4
化简求值(m+2/m²-2m)-（m-1/m²-4m+4）÷（m-1/m） 其中m=4
已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
解方程 2m-m*m 1=2(m*m-2m)(m*m-2m)
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
当m= 时,2m(3m-5)+3m(1-2m)=14
若m^2+m=1,则2m^4+2m^3+2m+2012
