Question

（x-y)的立方×（x-y)的平方×（y-x)=? 步骤 急O(∩_∩)O谢谢

Answer 1

(x-y)³×(x-y)²×(y-x)
=(x-y)³×(x-y)²×[-(x-y)]
=-(x-y)^(3+2+1)
=-(x-y)^6

(x-y)^6表示(x-y)的6次方

Answer 2

解: （x-y)的立方×（x-y)的平方×（y-x)
=(x-y)³×(x-y)²×[-(x-y)]
=-(x-y)^6

祝你学习进步,如有不明可以追问.同意我的答案请采纳,O(∩_∩)O谢谢

Answer 3

（x-y)^3×（x-y)^2×（y-x)
=（x-y)^3×（x-y)^2×[-（x-y)]
=-(x-y)^(3+2+1)

=-(x-y)^6

Answer 4

(X-Y)~3x(X-y)~2x[-(X-Y)]=(x-y)~3x[-(x-y)~3]=-(x-y)`6

Answer 5

=(x-y)³×（x-y)²×[-（x-y)]
=(x-y)³×[-(x-y)³]
=-(x-y)6
