M^2代表M的平方,以此类推……
(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
要有过程(最好讲解一下),谢谢
跟(a^2+b^2)=(a+b)^2-2ab有关吗 展开

(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
=3*(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^2-1)*(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^4-1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^8-1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^16-1)(2^16+1)(2^32+1)/3
=(2^32-1)/3
=3*(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^2-1)*(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^4-1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^8-1)(2^8+1)(2^16+1)(2^32+1)/3
=(2^16-1)(2^16+1)(2^32+1)/3
=(2^32-1)/3
追问
=(2^2-1)*(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)/3
这部讲一下
追答
2^2-1=3
