(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1))(2^32+1)+1的末位数字是?(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1))(2^32+1)+1的末位
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1))(2^32+1)+1的末位数字是?
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1))(2^32+1)+1的末位数字是?
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1))(2^32+1)+1的末位数字是?
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1))(2^32+1)+1
=(2-1)(2+1)(2^2+1)...(2^16+1)(2^32+1)+1
=(2^2-1)(2^2+1)...(2^32+1)+1
=...
=(2^32-1)(2^32+1)+1
=2^64-1+1
=2^64
2^n的个位是以:2、4、8、6循环
64/4=16
没有余数,说明个位是:6
是6挖 前面的末位 是5 加一就是6
6
2
(1+1/2)(1+1/2^2)(1+1/2^4)^(1+1/2^32)
计算:(2+1)({2}^{2}+1)({2}^{4}+1)({2}^{8}+1)...({2}^{256}+1)
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^2048+1),
(2+1)(2^2-1)(2^4+1)(2^8+1)(2^16-1)(2^32+1)(2^64+1)
(1+1/2)(1+1/2^2)(1+1/2^4)(1+1/2^8)+1/2^15
计算:(1+2)(1+2^2)(1+2^4)(1+2^8)(1+2^16)(1+2^32)(1+2^64)
(-2k-1)^2+4(-k^2+1)
(2^2+1)*(2^4+1)*(2^8+1)*(2^16+1)*(2^32+1)
-1/2+(-1/6)-(-1/4)-2/3
