化简:(2+1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1 最好有讲解~
答
(2+1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1
=(2-1)(2+1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1
=(2^2-1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1
=(2^4-1)(2^3+1)(2^4+1)(2^8+1)+1
=(2^3+1)(2^4-1)(2^4+1)(2^8+1)+1
=(2^3+1)(2^8-1)(2^8+1)+1
=(2^3+1)(2^16-1)+1
=9*(2^16-1)+1
=9*2^16-9+1
=9*2^16-8
=589816
答
(2+1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1=(2-1)(2+1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1=(2^2-1)(2^2+1)(2^3+1)(2^4+1)(2^8+1)+1=(2^4-1)(2^3+1)(2^4+1)(2^8+1)+1=(2^8-1)(2^3+1)(2^8+1)+1=(2^16-1)(2^3+1)+1=2^...
