(2-1)乘(2+1)乘(2^2+1)乘(2^4+1)乘(2^8+1)乘(2^16+1)乘(2^32+1)要过程和答案
(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
原式=(2^2-1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1
=(2^4+1)(2^4-1)(2^8+1)(2^16+1)(2^32+1)+1
=(2^8-1)(2^8+1)(2^16+1)(2^32+1)+1
=(2^16-1)(2^16+1)(2^32+1)+1
=(2^32-1)(2^32+1)+1
=(2^64-...
全部展开
原式=(2^2-1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1
=(2^4+1)(2^4-1)(2^8+1)(2^16+1)(2^32+1)+1
=(2^8-1)(2^8+1)(2^16+1)(2^32+1)+1
=(2^16-1)(2^16+1)(2^32+1)+1
=(2^32-1)(2^32+1)+1
=(2^64-1)+1
=2^64
=(2^4)^16
=16^16
个位永远是6*6*6*……
所以不用计算机可得出个位是6
