(2+1)(2^2+1)(2^4+1)(2^8+1)
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)
=2^16-1
=65535

利用平方差公式计算: (2+1)(2^2+1)(2^4+1)(2^8+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

平方差公式是“(a-b)*(a+b)=a^2-b^2”对吧?但是观察题目里的式子,显然少了(a-b)这一项(因为题目里都是加号的项,却唯独没有减号项),因此,我们便来人为地添上一个减号——分子分母同乘(2-1):原式=(2-1)*[(2+1)*(2^2+1)*(2^4+1)*(2^8+1)+1]\/(2-1)=[(2-1...

(2+10)(2^2+1)(2^4+1)(2^8+1)计算,
若是,解答如下:(2+1)(2^2 +1)(2^4 +1)(2^8 +1)=(2-1)(2+1)(2^2 +1)(2^4 +1)(2^8 +1) (利用平方差公式)=(2^2 -1)(2^2 +1)(2^4 +1)(2^8 +1)=(2^4 -1)(2^4 +1)(2^8 +1)=(2^8 -1)(2^8 +1)=2^16 -1 =65535 (3x-2)²-(...

2+1)(2的平方+1)(2的四次方+1)(2的八次方+1)
用平方差公式 (2+1)(2的平方+1)(2的四次方+1)(2的八次方+1)=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)=(2^2-1)(2^2+1)(2^4+1)(2^8+1)=(2^4-1)(2^4+1)(2^8+1)=(2^8-1)(2^8+1)=2^16-1

(2+1)(2^2+1)(2^4+1)(2^8+1)
(2+1)(2^2+1)(2^4+1)(2^8+1)=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)=(2²-1)(2^2+1)(2^4+1)(2^8+1)=(2^4-1)(2^4+1)(2^8+1)=(2^8-1)(2^8+1)=2^16-1

(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)+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 (连续使用平方差公式)...
