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=(3^8-1)(3^8+1)(3^16+1)(3^32+1)+1=(3^16-1)(3^16+1)(3^32+1)+1=(3^32-1)(3^32+1)+1=(3^64-1)+1=3^64=9^32=(10-1)^32所以是32位
