1.(-0.5)^101×2^×2^101 2.(1、2xy^2)^3-1/6x(xy^3)^2 3.(-0.25)^2005×4^2006
1.(-0.5)^101×2^101
=(-0.5×2)^101
=(-1)^101
=-1
2.(1、2xy^2)^3-1/6x(xy^3)^2
=1/8x^3y^6-1/6x^3y^6
=-1/24x^3y^6
3.(-0.25)^2005×4^2006
=(-0.25)^2005×4^2005×4
=[(-0.25)×4]^2005×4
=(-1)^2005×4
=-4
=(-0.5×2)^101
=(-1)^101
=-1
2.(1、2xy^2)^3-1/6x(xy^3)^2
=1/8x^3y^6-1/6x^3y^6
=-1/24x^3y^6
3.(-0.25)^2005×4^2006
=(-0.25)^2005×4^2005×4
=[(-0.25)×4]^2005×4
=(-1)^2005×4
=-4
先化简,再求值 ⒈2(Xy+Xy)-3(Xy-xy)-4Xy,其中X=1,y=-1
1-(3xy-x)+【-2(2x+3xy)】
计算3xy[2xy-x(y-2)+x-1]
5x^2y/-1/2xy*3xy^2
y^3+xy^2+2xy+x^2-1 因式分解
3xy-3xy-xy+2yx
xy(xy+1)+(xy+3)-2(x+y+2分之一)-(x+y-1)的平方
(-3分之1xy)的平方×[xy(2x-y)-2x(xy-y的平方)]
化简!1、(x^2-xy)+xy+y^2 2、3(x^2-xy)-xy+y^2
当x=3,y=3分之1时,求代数出3xy-[2xy-2(xy-2分之3xy)+xy]+3xy的值
[3xy(1-x)-6xy(x-1/2)]*2x*(-xy)平方,x=-1 y=2 ; 3xy平方(-1/3x平方y+4
-3(2x^2-xy)+4(x^2+xy-6)
