分式的乘除 计算(x²-y²/xy)²÷(x+y)· (x/x-y)³
分式计算:(x²+2xy+y²)/(x²y+xy)*y/(x+y)
(xy-x²)²÷(x-y)²/xy·x-y/x² 计算
初中分式计算:(xy-x²)·xy/x-y
计算,(x^2-xy)/(xy^2)·y/(y-x) 分式的 乘法,
计算;(xy-x²)÷x²-2xy+y²/xy · x-y/x²
分式(x²-y²\xy)-(xy-y²\xy-x²)可化简为
计算:(xy-x²)乘 x-y分之xy
x-y/x²÷x²-2xy+y²/xy*(xy-x²)
[x(x²y²-xy)-y(x²-x³y)]÷3x²y
因式分解:[x(x²y²-xy)-y(x²-x³y)]÷3x²y
(急)计算(x²-y²/xy)²÷(x+y/y)²·(x/x-y)³
2x+y分之4x平方—4xy+y平方除以(4x平方—y平凡)分式的乘除
