2(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1等于多少
2(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1等于多少
2(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1
=(3-1)(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1
=(3^2-1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1
=(3^4-1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1
反复运用平方差公式
3^64-1+1
=3^64
原式
=(3-1)(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1
=(3^2-1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)+1
...
=(3^32-1)(3^32+1)+1
=3^64-1+1
=3^64
3的64次方,把开始的2看成(3-1)然后用平方差公式
