Question

再问你个计算题好不？ (x-y)(y-x)2(x-y)3 那个2、3是二次方和三次方啊~

gj2156你在吗？我就是在问你这道题哦~如果你看到了的话，就快点帮我解答吧~

Answer 1

(x-y)(y-x)²(x-y)³=(x-y)的6次方

追问

x-y和y-x可不是一回事啊！

追答

(x-y)²=(y-x)²

Answer 2

不好意思，才看到，让你久等了，哈
（x-y)(y-x)2(x-y)3=（x-y)(x-y)2(x-y)3=(x-y)^6

Answer 3

(X-Y)(Y-X)²(X-Y)³=(Y-X)²(X-Y)⁴=(X-Y)^6
(X-Y)²=(Y-X)²
