回答1:

原式=(5+1)(5-1)(5 2+1)(5 4+1)(5 8+1)乘四分之一-1
=(5 2-1)(5 2+1)(5 4+1)(5 8+1)乘四分之一-1
=(5 4-1)(5 4+1)(5 8+1)乘四分之一-1
= (5 8-1)(5 8+1)乘四分之一-1
=(5 的16次方-1)乘四分之一-1
然后结果不好些了

回答2:

6×26×626×390626+1=38146972655

回答3:

=(5-1)(5+1)(5^2+1)(5^4+1)(5^8+1)/4+1
=(5^2-1)(5^2+1)(5^4+1)(5^8+1)+1
=....
=5^16+1-1
=5^16(5^2是5的2次方)
