So sanh A va B biet : A=2006/2007+2007/2008+2008/2009 va B=(2006+2007+2008)/(2007+2008+2009)
so sanh M va N
M bang 2007/2008+2008/2009
N bang 2007+2008/2008+2009
So sánh :A=2008^2008 +1 /2008^2009 B =2008^2007 +1 /2008^2008+1
2. So sánh A và B:
A= 2006/2007 - 2007/2008 + 2008/2009 - 2009/2010
B=-1/2006*2007 - 1/2008*2009
so sanh cac so sau a) 3281 va 3190 b)11022009-11022008 va 11022008-11022007 c)A=(20082007+20072007)2008 va B=(20082008+20072008)2007
So sánh 2 biểu thức:
A = 2006/2007 + 2007/2008 + 2008/2009
B = 2006 + 2007 + 2008/2007 + 2008 + 2009
Tính nhanh :a)2/5+4/5 nhân 5/2
b)2008/2009-2009/2008+1/2009+2007/2008
So sánh:A=\(\frac{2008^{2008}+1}{2008^{2009}}\)
B=\(\frac{2008^{2007}+1}{2008^{2008}+1}\)
So sánh cặp số sau:
\(A=\frac{2006^{2007}+1}{2007^{2008}+1};B=\frac{2007^{2008}+1}{2008^{2009}+1}\)
Giúp!!!
