化简:[(x+y)^2n]^4÷(-x-y)^2n+1(n为正整数)

化简:[(x+y)^2n]^4÷(-x-y)^2n+1(n为正整数)
化简:[(x+y)^2n]^4÷(-x-y)^2n+1(n为正整数)

化简:[(x+y)^2n]^4÷(-x-y)^2n+1(n为正整数)
[(x+y)^2n]^4÷(-x-y)^2n+1
=-(x+y)^8n÷(x+y)^(2n+1)
=-(x+y)^(8n-2n-1)
=-(x+y)^(6n-1)

[(x+y)^2n]^4÷(-x-y)^(2n+1)
=(x+y)^8n÷【-(x+y)】^(2n+1)
=(x+y)^8n÷【-(x+y)^(2n+1)】
=-(x+y)^【8n-(2n+1)】
=-(x+y)^(6n-1).
