(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)+1
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)+1
=(2^2-1)(2^2+1)....(2^16+1)+1
=...
=(2^16-1)(2^16+1)+1
=2^32
希望我的回答对你有帮助,采纳吧O(∩_∩)O!
(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2-1)(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^2-1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^4-1)(2^4+1)…… (2^16+1)+1
=(2^16-1)(2^16+1)+1=(2^32-1)+1=2^32
因为(2-1)(2+1)(2^2+1)(2^4+1)…… (2^16+1)
=(2^2-1)(2^2+1)(2^4+1))…… (2^16+1)
=(2^4-)(2^4+1))…… (2^16+1)
=(2^8-1)(2^8+1)(2^16+1)
=(2^16-1)(2^16+1)
=2^32-1,
所以(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^32-1)/(2-1)+1=2^32。
左边乘以(2-1) 最后=2^32
(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2-1)(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^2-1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^4-1)(2^4+1)…… (2^16+1)+1
=2^32-1+1
=2^32
=4294967296
(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2-1)(2+1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^2-1)(2^2+1)(2^4+1)…… (2^16+1)+1
=(2^4-1)(2^4+1)…… (2^16+1)+1
......
=(2^16-1)(2^16+1)+1
=(2^32-1)+1
=2^32
