问题描述:
初中数学计算:(2+1)(2^2+1)(2^4+1)解:原式:(2-1)(2+1)(2^2+1)(2^4+1)=(2^2-1)(2^
计算:(2+1)(2^2+1)(2^4+1)
解:原式:(2-1)(2+1)(2^2+1)(2^4+1)
=(2^2-1)(2^2+1)(2^4+1)
=(2^4-1)(2^4+1)
=(2^8-1)
根据上面的计算方法,请计算
(3+1)(3^2+1)(3^4+1)×.×(3^32+1)-二分之三^64的值
亢世勇回答:
(3+1)(3^2+1)(3^4+1)×.×(3^32+1)-二分之三^64
=(3-1)(3+1)(3^2+1)(3^4+1)×.×(3^32+1)÷2-二分之三^64
=……
=(3的64次方-1)÷2-(3的64次方)÷2
=3的64次方÷2-1÷2-3的64次方÷2
=1÷2
=0.5
