(x-y)^5·(x-y)^4
=-(y-x)^5·(y-x)^4
=-(y-x)^9
=-[(y-x)^3]^3
(x-y)^5·(x-y)^4=-( )^3
(x-y)^5·(x-y)^4=-[(y-x)^3]^3 (x-y)^5·(x-y)^4 =-(y-x)^5·(y-x)^4 =-(y-x)^9 =-[(y-x)^3]^3
(x-y)^5*(x-y)^4=-( )^3
(x-y)^5*(x-y)^4=-【（y-x)³】^3
(x-y)的5次方*(x-y)的4次方等于-( )的三次方
括号填（X-Y）的三方
分解因式:(x-y)^5+(y-x)^3 麻烦解一下
=(x-y)^5-(x-y)^3 =(x-y)^3{(x-y)^2-1} =(x-y)^3(x-y+1)(x-y-1)
(x-y)^5\/(y-x)^3=?
-(x-y)^2
(x-y)^5\/(y-x)^4等于什么
(x-y)^5\/(y-x)^4 = (x-y)^5\/(x-y)^4 =x-y
(x-y)的5次方*(y-x)的3次方*(x-y)=?
-(x-y)的9次方
(x+y)(x-y)^5
(x+y)(x--y)^5=(x^2--y^2)(x--y)^4 =(x^2--y^2)(x^2--2xy+y^2)^2 =(x^2--y^2)(x^4+4x^2y^2+y^4--4x^3y+2x^2y^2--4xy^3)=x^6+4x^4y^2+x^2y^4--4x^5y+2x^4y^2--4x^3y^3--x^4y^2--4x^2y^4--y^6+4x^3y^3 --2x^2y^4+4xy^5 =x^...
因式分解 (x-y)的5次方+(y-x)的3次方
(x-y)的5次方+(y-x)的3次方 =(x-y)的5次方-(x-y)的3次方 =（x-y）³【（x-y）²-1】=（x-y）³（x-y+1）（x-y-1）
-(x-y)^5(y-x)^4怎么算
解：--(x--y)^5(y--x)^4 =(y--x)^5(y--x)^4 =(y--x)^9.
