(x-1)(x+1)(x²+1)(x^4+1)(x^8+1)=?有讲解更好
网友回答
(x-1)(x+1)(x²+1)(x^4+1)(x^8+1)
=(x²-1)(x²+1)(x^4+1)(x^8+1)
=(x^4-1)(x^4+1)(x^8+1)
=(x^8-1)(x^8+1)
=x^16-1
======以下答案可供参考======
供参考答案1:
=(x²-1)(x²+1)(x^4+1)(x^8+1)
=(x^4-1)(x^4+1)(x^8+1)
=(x^8-1)(x^8+1)
=(x^16-1)
供参考答案2:
=(x²-1)(x²+1)(x^4+1)(x^8+1)
=(x^4-1)(x^4+1)(x^8+1)
=(x^8-1)(x^8+1)
=x^16 -1
