化简:(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)...…(x^1024+1)(x^2009+1)(x-1)
解:原式=(x-1)(x+1)(x²+1)(x⁴+1).......(x^1024+1)(x^2009+1)
=(x²-1)(x²+1)(x⁴+1)........(x^1024+1)(x^2009+1)
=(x⁴-1)(x⁴+1)........(x^1024+1)(x^2009+1)
=(x^2048-1)(x^2009+1)

(x+1)(x^2+1)(x^4+1)…(x^2009+1)(x-1)
=(x+1)(x-1)(x^2+1)(x^4+1)…(x^2009+1)
=(x^2-1)(x^2+1)(x^4+1)…(x^2009+1)
=……
=x^4018-1

:(x+1)(x^2+1)(x^4+1)…(x^2009+1)(x-1)
=﹙x-1﹚(x+1)(x^2+1)(x^4+1)…(x^2009+1)
=﹙x²-1﹚(x^2+1)(x^4+1)…(x^2009+1)
=﹙x^4-1﹚﹙x^4+1﹚·····﹙x^2009+1﹚
=﹙x^8-1﹚···﹙x^2009+1﹚
题目再看看,有问题

(x-1)(x+1)(x^2+1)(x^4+1)…(x^2009+1)
=(x^2-1)(x^2+1)(x^4+1)…(x^2009+1)
=x^4018-1
