计算(x^2+2xy+y^2)(x^2-xy+y^2)^2
计算(x^2+2xy+y^2)(x^2-xy+y^2)^2
(x^2+2xy+y^2)(x^2-xy+y^2)^2
=(x+y)^2(x^2-xy+y^2)^2
=[(x+y)(x^2-xy+y^2)]^2
=(x^3+y^3)^2
=x^6+2x^3y^3+y^6
（x^2+xy/x-y)/（xy/x-y)计算 x-y/xy-y^2计算 计算（xy-y^2)÷x-y/xy 计算3xy[2xy-x(y-2)+x-1] 计算：3xy[2xy-x（y-2）+x] （xy-x^2)乘以(xy)/(x-y) 计算：x²+2xy+y²/xy-y².x²-2xy+y²/xy+y&# 计算：(x+y/x-y)÷(xy+x^2) 计算：y/(x的平方-xy)+2/(y-x)-x/(y的平方-xy) 计算:4xy-(x+y)^2/xy(x+y)(x-y)÷x^2+xy-2y^2/x^2y+2xy^2 计算(x-y)(x^2+xy+y^2)得 计算：(X+Y)(X^2-XY+Y^2)
