(1-1/2+1/3-1/4.-1/100)
=(1+1/2+1/3+1/4.+1/100)-2*(1/2+1/4+1/6+.1/100)
=(1+1/2+1/3+1/4.+1/100)-(1+1/2+1/3+1/4+.1/50)
=1/51+1/52+1/53.+1/100
所以你的答案是1,懂了嗎?
最好教會她自己研究,我以前也沒遇到這種問題,但只要領(lǐng)悟了數(shù)學(xué),其實這種變換很簡單的.
差點跟著一起錯,題目你肯定打錯了.
(1-1/2+1/3-1/4.-1/100)/(1/50+1/51+1/52.+1/100)=?
(1-1/2+1/3-1/4.-1/100)/(1/50+1/51+1/52.+1/100)=?
