(1/3m-1/2)^2
(1/3m-1/2)^2
(1/3m-1/2)^2
(1/9m^2)-1/4
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
2m/m^2-9-1/m+3(计算)
若多项式5x*x-2mxy-3y*y+4xy-3x+1中不含xy项,求(-(m*m*m)+2(m*m)-m+1)-(m*m*m+2m*m-m+4)
m(m+1)(m+2)(m+3)+1?
1/m(m+1)+1/(m+1)(m+2)+1/(m+2)(m+3)+.+1/(m+9)(m+10)
(m²-2m+1/m²-1+m²-m/m)÷(1+m/2,其中m=-3)
分解因式(1)m²+m-6;(2)m³+4m²+4m;(3)-m³+2m²-m
m^2+m-6/m^2+2m+1÷m+3/m^+m·m^2-1/2-m 其中m=-1/2
3(m+1)^2-5(m+1)+2(m-1)^2其中m=-5
(m-1/3-m-1)÷m-2/2m-2等于多少?
m*m-5m-1=0则2m*m-5m+1/m*m
已知m*m+m-1=0,求m*m*m+2m*m-2005
(12m+1)(2m-3)-(6m+5)(6m+5)
(m+m^-1+2)/(m^-1/2+m^1/2)*(m^-2/3-m3/2)/(m+m^-1+1)
(3m^3-2m^2+m)-(4m^3-2m^2+3m),其中m=-1; 求答案
若(2+根号3)^^m=1,求m²-1/m+1-m²-m/根号m²-2m+1的值
3(m-1)²+(m+2)(m²-2m+4)-m(m²+3m-3)
已知m=根号3,求(1-2m+m平方)/(m-1)-(m-1)/(m²-m)的值
