(x-y)²×(y-x)³ 等于多少 解法.
(x-y)²×(y-x)³ 等于多少 解法.
(x-y)²×(y-x)³ 等于多少 解法.
(x-y)²×(y-x)³ 因为(x-y)²=(y-x)²,所以
=(y-x)²×(y-x)³
=(y-x)^5 (y-x)的五次方
原式=(x-y)^2*(-1)^3*(x-y)^3
=-(x-y)^5
满意请采纳,谢谢~
=(x-y)²×[-(x-y)³]
=-(x-y)的5次方
﹙x-y)²×﹙y-x)³=﹙y-x)²×﹙y-x)³=﹙y-x)^5.
(x-y)²×(y-x)³
=(y-x)²(y-x)³
=(y-x)^5
(x-y)^2*(y-x)^3=(y-x)^2(y-x)^3..
=(y-x)^5.
或,
原式=(y-x)^4*(y-x).
=(x-y)^4*[-(x-y)}.
=-(x-y)^5.
