(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
=(2^4-1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
=(2^8-1)(2^8+1)(2^16+1)(2^32+1)
=(2^16-1)(2^16+1)(2^32+1)
=(2^32-1)(2^32+1)
=2^64-1
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)

原式=(2-1)*[(2+1)*(2^2+1)*(2^4+1)*(2^8+1)+1]/(2-1)
=[(2-1)*(2+1)*(2^2+1)*(2^4+1)*(2^8+1)+(2-1)*1]/1
=(2^2-1)*(2^2+1)*(2^4+1)*(2^8+1)+1
=(2^4-1)*(2^4+1)*(2^8+1)+1
=(2^8-1)*(2^8+1)+1
=2^16-1+1
=2^16
=[(2-1)*(2+1)*(2^2+1)*(2^4+1)*(2^8+1)+(2-1)*1]/1
=(2^2-1)*(2^2+1)*(2^4+1)*(2^8+1)+1
=(2^4-1)*(2^4+1)*(2^8+1)+1
=(2^8-1)*(2^8+1)+1
=2^16-1+1
=2^16
