(x-y)²(x+y)²(x²-xy+y²)²(x²+xy+y²)² 等于几?

(x-y)²(x+y)²(x²-xy+y²)²(x²+xy+y²)²
=[(x+y)(x²-xy+y²)]²[(x-y)²(x²+xy+y²)]²
=(x³+y³)²(x³-y³)²
=[(x³+y³)(x³-y³)]²
=(x^6-y^6)²
=x^12-2x^6y^6+y^12

x²/xy-x/y 计算：(xy-x²)×x-y/xy [-xy/(x-y)²]²×(y²-xy/x)³ x/xy-y²与y/x²-xy 通分 x-y/x²÷x²-2xy+y²/xy*（xy-x²）计算：（xy-x²）乘 x-y分之xy 计算：x²+2xy+y²/xy-y².x²-2xy+y²/xy+y&# (x+y)(x²-xy+y²）—xy（x+y）因式分解 (xy-x²）²÷（x-y)²/xy·x-y/x² 计算因式分解：(x-y)²-xy²+x²y (x-y)²-xy²+x²y 因式分解 -x³y³-x²y²+xy
