...×(y-x)五次方 等于多少, 求过程 详细 急急急急急
(x-y)³×(y-x)²×(y-x)五次方 =【-(y-x)³】×(y-x)²×(y-x)五次方 =-(y-x)的(3+2+5)次方 =-(y-x)的10次方
(x-y)³×(y-x)²×(y-x)五次方 等于多少,急
(x-y)³×(y-x)²×(y-x)五次方 =【-(y-x)³】×(y-x)²×(y-x)五次方 =-(y-x)的(3+2+5)次方 =-(y-x)的10次方
(x-y)²×(y-x)³ 等于多少 求过程 解法。
解: (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 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
(x-y)²×(y-x)³
(x-y)²×(y-x)³=(y-x)²×(y-x)³=(y-x)的5次方 ^__^真心祝你学习进步,如果你对这个答案有什么疑问,请追问,另外如果你觉得我的回答对你有所帮助,请千万别忘记采纳哟!
(x-y)的五次方=?
(x-y)的五次方 =(x-y)²(x-y)³=(x²-2xy+y²)(x^3-3x^2y+3xy^2-y^3)=x^5-5x^4y+10x^3y^2-10 x^2y^3+5xy^4+y^5
(x-y)²+y(y-x)因式分解?
因式分解 (x-y)²+y(y-x)=(x-y)²-y(x-y)=(x-y-y)(x-y)=(x-2y)(x-y)
(x-y)³÷(y-x)²等于多少?
(x-y)³÷(y-x)²=(x-y)³÷(x-y)²=x-y
(x-y)³.(x-y)².(y-x)
(x-y)³.(x-y)².(y-x)=(x-y)³.(x-y)².【-(x-y)】=-(x-y)^6
(x-y)²(y-x)²=
(x-y)²(y-x)²=(x-y)^4
因式分解(x-y)²-(y-x)
(x-y)²-(y-x)=(x-y)²+(x-y)=(x-y)(x+y+1),错在没有转化-(y-x)=x+y上!
