(x+1/x)(x^2+1/x^2)(x^4+1/x^4)...(x^16+1/x^16)(x^2-1)
(x+1/x)(x^2+1/x^2)(x^4+1/x^4)...(x^16+1/x^16)(x^2-1)
(x+1/x)(x^2+1/x^2)(x^4+1/x^4)...(x^16+1/x^16)(x^2-1)
(x^2-1)拆开为x(x-1/x),(x-1/x)挪到最前面
(x+1/x)(x^2+1/x^2)(x^4+1/x^4)...(x^16+1/x^16)(x^2-1)
=(x-1/x)(x+1/x)(x^2+1/x^2)(x^4+1/x^4)...(x^16+1/x^16)x
=(x^2-1/x^2)(x^2+1/x^2)(x^4+1/x^4)...(x^16+1/x^16)x
=.
=(x^16-1/x^16)(x^16+1/x^16)x
=(x^32-1/x^32)x
=x^33-1/x^31
