原式=(3-2)(3+2)(3^+2^)(3^4+2^4)(3^8+2^8)/(3-2)
=(3^-2^)(3^+2^)(3^4+2^4)(3^8+2^8)/(3-2)
=(3^4-2^4)(3^4+2^4)(3^8+2^8)/(3-2)
=(3^8-2^8)(3^8+2^8)/(3-2)
=(3^16-2^16)/(3-2)
=3^16-2^16
=43046721-65536(可借助科学计算器)

(3+2)(3^2+2^2)(3^4+2^4)(3^8+2^8)
=(3-2)(3+2)(3^2+2^2)(3^4+2^4)(3^8+2^8)
=(3^2-2^2)(3^2+2^2)(3^4+2^4)(3^8+2^8)
=(3^4-2^4)(3^4+2^4)(3^8+2^8)
=(3^8-2^8)(3^8+2^8)
=3^16-2^16
