若A=(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1),求A的值.若A=(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^3

若A=(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1),求A的值.
若A=(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1),求A的值.

若A=(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1),求A的值.
2^128-1
具体就是:
A=(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1)
=(2^4-1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)(2^64+1)
=.
=(2^64-1)(2^64+1)
=2^128-1
提示:用(x+y)(x-y)=x^2-y^2.

你无聊?

2^128+1

^啥意思次方昂不知道吗?。。。懂了会做吗?教我我在做我在做这是几年级的题好像是初二。。。好吧。。。好吧兄台,恕我无能为力,饭吃了在想。。。sorry啊没事
