(x-y)^2n(x-y)^(2n+1)*(y-x)怎么计算(x-y)^2n(x-y)^(2n+1)*(y-x)怎么计算(x-y)^2n(x-y)^(2n+1)*(y-x)怎么计算(x-y)^2n(x
(x-y)^2n(x-y)^(2n+1)*(y-x) 怎么计算
(x-y)^2n(x-y)^(2n+1)*(y-x) 怎么计算
(x-y)^2n(x-y)^(2n+1)*(y-x) 怎么计算
(x-y)^2n(x-y)^(2n+1)*(y-x)
=-(x-y)×(x-y)^2n×(x-y)^(2n+1)
=-(x-y)^(2n+1)×(x-y)^(2n+1) //:底数相同指数相加;
=-(x-y)^[2(2n+1)]
