(x-y)^4*(y-x)^3*(x-y)=?--------- (2xyz^2)^2*(-xy^2z)-(-xyz)^3*(5yz)*(-3z)=?
(x-y)^4*(y-x)^3*(x-y)=？---------
(2xyz^2)^2*(-xy^2z)-(-xyz)^3*(5yz)*(-3z)=?

(x-y)^4*(y-x)^3*(x-y)=-(x-y)^4*(x-y)^3*(x-y)=-(x-y)^(4+3+1)=-(x-y)^8
(2xyz^2)^2*(-xy^2z)-(-xyz)^3*(5yz)*(-3z)=4x^2y^2z^4*(-xy^2z)+(x^3y^3z^3)*(5yz)*(-3z)
=-4x^3y^4z^5-15x^3y^4z^5=-19x^3y^4z^5

XYZ满足XY/X+Y=-2,YZ/Y+Z=3/4,ZX/Z+X=-4/3,求XYZ/XY+YZ+ZX的值已知三个数x,y,z,满足xy/x+y=-2，yz/y+z=4/3,zx/z+x=-4/3,求(xyz)/(xy+yz+ 先化简再求值3xyz+2(x^2y+y^2z-xyz)-xyz+2z^2x x=1 y= -1 z=2 x:y:z=2:3:4且x+y+z=18求xyz 已知x^3+y^3-z^3=96,xyz=4,x^2+y^2+z^2-xy+xz+yz=12,则x+y-z等于 (x-3y+z)^2+/ 5x-4y+z/=0 且xyz≠0 xy+yz+zx/x^2+y^2+z^2 因式分解 (x+y+z)^2+yz(y+z)+xyz (2x^3-xyz)-2(x^3-y^3+xyz)+(xyz-2y^3),其中x=-1,y=-2,z=-3. 已知:A=2x^3-xyz,B=y^3-z^3+xyz,C=-x^3+2y^2-xyz,且(x+1)^2+|y-1|+| 已知xyz适合关系式√3x+y-z-2+√2x+y-z=√x+y-2011+2011-x-y,试求xyz的值方程组X:Y:Z=4:7:8,X+Y+2Z=54 求XYZ 已知x+y+z=3,xy+yz+xz=-1,xyz=2,求x^2y^2+y^2z^2+x^2z^2
