Cho S=1/11+1/12+1/13+1/14+1/15+1/16+1/17+1/18+1/19+1/20
HÃY SO SÁNH S VOI 1/2
so sanh:1/2+1/4+1/8+1/16+............+1/512 voi 1
So sanh :
A = 1/2 + 1/4+ 1/8 + 1/16 + 1/32 voi 2005/2006
So sanh 1/4+1/9+1/16+1/25+1/36+...+1/10000 voi 1 va neu cach giai(so sanh) nua nhe!
cho s=1/11+1/12+1/13+1/14+1/15+1/16+1/17+1/18+1/19+1/20. hãy so sánh với 1/2
S = 1/11 + 1/12 + 1/13 + 1/14 + 1/15 + 1/16 + 1/17 + 1/18 + 1/19 + 1/20
So sánh S và 1/2
So sanh A voi 1
A= 1/4 + 1/9 + 1/16 +.........+1/2500
cho A=1/4+1/9+1/16+1/25+...+1/10000 so sanh A voi 3/4
S = 1/11+1/12+1/13+1/14+1/15+1/16+1/17+1/18+1/19+1/20
Hãy so sánh S và 1/2.
