(a+1)(a^2+1)(a^4+1)`````(a^1024+1),其中a不等于0

问题描述:

(a+1)(a^2+1)(a^4+1)`````(a^1024+1),其中a不等于0

(a+1)(a^2+1)(a^4+1)`````(a^1024+1)
=(a+1)(a^2+1)(a^4+1)`````(a^1024+1)(a-1)/(a-1)
=(a^2-1)(a^2+1)(a^4+1)`````(a^1024+1)/(a-1)
=(a^4-1)(a^4+1)`````(a^1024+1)/(a-1)
=(a^8-1)`````(a^1024+1)/(a-1)
=(a^1024-1)`````(a^1024+1)/(a-1)
=(a^2048-1)/(a-1)再问一个。。。(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1=(2^2-1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1=(2^4-1)(2^4+1)(2^8+1)(2^16+1)(2^32+1)+1=(2^8-1)(2^8+1)(2^16+1)(2^32+1)+1=(2^16-1)(2^16+1)(2^32+1)+1=(2^32-1)(2^32+1)+1=(2^64-1)+1=2^64再问。。。我知道你狠受不了。。。100^2-99^2+98^2-97^2+96^2-95^2+``````+2^2-1^2 .答完了一定加分的。。。。100^2-99^2+98^2-97^2+96^2-95^2+``````+2^2-1^2 .=(100+99)(100-99)+(98+97)(98-97)+...(2+1)(2-1)=199+195+。。。3=50*(199+3)/2=5050
