(2+1)×(2²+1)×(2的四次幂+1)×(2的八次幂+1)+1
=(2-1)*(2+1)×(2²+1)×(2的四次幂+1)×(2的八次幂+1)+1
=(2²-1)(2²+1)×(2的四次幂+1)×(2的八次幂+1)+1
=(2的四次幂-1)(2的四次幂+1)×(2的八次幂+1)+1
=(2的八次幂-1)(2的八次幂+1)+1
=(2的十六次幂-1)+1
=2的十六次幂
(2+1)×(2²+1)×(2的四次幂+1)×(2的八次幂+1)+1
=(2-1)x(2+1)×(2²+1)×(2的四次幂+1)×(2的八次幂+1)+1
=(2^2-1)x(2^2+!)x...
=2^16-1+1
=2^16
