C1: \(1-\frac{2}{5}=\frac{3}{5}\)
\(1-\frac{11}{14}=\frac{3}{14}\)
Vì \(\frac{3}{5}>\frac{3}{14}\Rightarrow\frac{2}{5}
C1: \(1-\frac{2}{5}=\frac{3}{5}\)
\(1-\frac{11}{14}=\frac{3}{14}\)
Vì \(\frac{3}{5}>\frac{3}{14}\Rightarrow\frac{2}{5}
So sanh 1/5+1/14+1/28+1/44+1/61+1/85+1/97 va 1/2
So sanh A va B
A=-1/2011-3/11^2-5/11^3-7/11^4
B=-1/2011-7/11^2-5/11^3-3/11^4
so sanh
1/5+1/14+1/28+1/44+1/61+1/85+1/97 va 1/2
BT1: So sanh
\(\frac{-13}{39}va-\frac{21}{63}\)
\(\frac{1}{234567}va-\frac{2}{14}\)
BT2: So sanh
\(\frac{-39}{65}va-\frac{21}{35}\)
\(\frac{1}{2012}va-\frac{1}{14}\)
X=2/7 va y=-3/11
so sanh
So sanh A va B biet
A = -2 /2011 -3/112 -5/113- 7/114
B = -1/2011 - 7/112 -5/113 - 3/114
so sanh A va B:A=(20^2004+11^2004)^2005 va B = (20^2005+11^2005)^2004
Cho A= 1+2+2^2+2^3+.....+2^10. So sanh A va 2^11
cho 2 phân số hữu tỉ x=\(\frac{-5}{8}\);y=\(\frac{14}{-17}\).Hãy so sanh x va y theo 4 cách
