计算(x-y)的n次方*[(y-x)的3次方+5(x+y)的n次方(y-x)的2n次方]=______(n为正整数)

计算(x-y)的n次方*[(y-x)的3次方+5(x+y)的n次方(y-x)的2n次方]=______(n为正整数)
计算(x-y)的n次方*[(y-x)的3次方+5(x+y)的n次方(y-x)的2n次方]=______(n为正整数)

计算(x-y)的n次方*[(y-x)的3次方+5(x+y)的n次方(y-x)的2n次方]=______(n为正整数)
你这是要填什么的?
(x-y)的n次方*[(y-x)的3次方+5(x+y)的n次方(y-x)的2n次方]
=(x-y)的n次方*[-(x-y)的3次方+5(x+y)的n次方(x-y)的2n次方]
=-(x-y)的(n+3)次方+5(x+y)的n次方(x-y)的(n+2n)次方
=-(x-y)的(n+3)次方+5(x+y)的n次方(x-y)的3n次方
