(x-y)2的次方·(y-x)4的次方·(y-x)3的次方=
(x-y)²[(y-x)^4](y-x)³=(y-x)²[(y-x)^4](y-x)³=(y-x)^9
(x-y)2次方×(y-x)的4次方×(y-x)的3次方。怎么计算要详细过程!详细过 ...
(x-y)^2*(y-x)^3*(x-y)^4 =(x-y)^(2+4)*(y-x)^3 ==(x-y)^6*(y-x)^3 =(y-x)^6*(y-x)^3 =(y-x)^9
(x-y)的二次方乘以(y-x)的三次方等于多少
(X-Y)^2=(Y-X)^2=Y^2-2XY+X^2 (Y-X)^3=Y^3-3Y^2X+3YX^2-X^3 所以原式=(Y-X)^5
(x-y)的2次方×(y-x)的3次方×(x-y)的4次方
=(y-x)的2次方×(y-x)的3次方×(y-x)的4次方 =(y-x)的(2+3+4)次方 =(y-x)的9次方
(x-y)的2次方·(x-y)的3次方·(y-x)的2次方·(y-x)的3次方
(x-y)的2次方·(x-y)的3次方·(y-x)的2次方·(y-x)的3次方 =·(x-y)的5次方·(y-x)的5次方 =-(x-y)的5次方·(x-y)的5次方 =-(x-y)的10次方
x减y括号的平方乘以y减x刮号的3次方等于
(X-Y)^2(Y-X)^3 =(Y-X)^2*(Y-X)^3 =(Y-X)^5。其中 (X-Y)^2=(Y-X)^2,不用变符号。
(x-y)的2次方乘(y-x)的3次方等于?
(x-y)的2次方乘(y-x)的3次方 =(y-x)的2次方乘(y-x)的3次方 =(y-x)的5次方 祝你学习进步,有不明白的可以追问!谢谢!!
(x-y)^2乘(y-x)^3的结果为?
(x-y)^2*(y-x)^3=(x-y)^2*(-(x-y)^3)=-(x-y)^5=(y-x)^5
(x-y)的2次方-(y-x)的3次方(因式分解)
(x-y)的2次方-(y-x)的3次方=(x-y)^2(1+x-y)
(x-y)的2次方×(y-x)的3次方×(x-y)=
(x-y)的2次方×(y-x)的3次方×(x-y)=-(x-y)^(2+3+1)= -(x-y)^6 (y-x)的3次方=-(x-y)^3
