(2+1)(2的平方+1)(2的4次+1)(2的8次+1)(2的16次+1)+1=?
问题描述:
(2+1)(2的平方+1)(2的4次+1)(2的8次+1)(2的16次+1)+1=?
答
(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)(2^4+1)(2^8+1)(2^16+1)+1
=(2^4-1)(2^4+1)(2^8+1)(2^16+1)+1
=(2^8-1)(2^8+1)(2^16+1)+1
=(2^16-1)(2^16+1)+1
=(2^32-1+1)
=2^32
