\(A=2012.2010+\frac{2013}{2011}.2011+2012\)
\(\Rightarrow A=4044120+2013+2012\)
\(\Rightarrow A=4044120+4025\)
\(\Rightarrow A=4048145.\)
Vậy \(A=4048145.\)
a = 2010/2011 + 2011/2012 + 2012/2013 so sánh a và b
b = 2010/2011 + 2011/2012 + 2012/2013
Không tính cụ thể , hãy sắp xếp các biểu thức sau theo thứ tự giảm dần :
\(\frac{\frac{2010}{2011}}{\frac{2012}{2013}}+\frac{\frac{2011}{2012}}{\frac{2013}{2014}}+\frac{\frac{2012}{2013}}{\frac{2014}{2015}}\)
\(\frac{\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2013}}{\frac{2012}{2013}+\frac{2013}{2014}+\frac{2014}{2015}}\)
\(\frac{\frac{2010+2011+2012}{2011+2012+2013}}{\frac{2012+2013+2014}{2013+2014+2015}}\)
\(\frac{\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2013}}{\frac{2012+2013+2014}{2013+2014+2015}}\)
\(\frac{\frac{2010+2011+2012}{2011+2012+2013}}{\frac{2012}{2013}+\frac{2013}{2014}+\frac{2014}{2015}}\)
So sánh:\(\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2013}+\frac{2013}{2014}\)và\(\frac{2010}{2008}+\frac{2011}{2013}+\frac{2012}{2014}+\frac{2013}{2015}\)
so sanh :
a=2010 /2011 +2011/2012 +2012/2013
b =2010+2011+2012 /2011 +20120 +2012
so sanh 1/51+1/52 +1/53 +.......+1/60 voi:
a .1/5
b.1/6
tra loi nhanh ho minh nha !
2011/2010 *2012/2011 * 2013/2012 * 2014/2013 * 1005/1007
dấu * là dấu nhân
Cho A=2010+2011*2012;B=2012*2013-2014.Tính A/B
Cho A=2010+2011*2012;B=2012*2013-2014 .Tính A/B.
so sánh a với 1 biết :
2012*2010+2013
2011*2011+2012
giúp mik với
Cho A = 2010+ 2011 x 2012 ; B = 2012 x 2013 – 2014
Tính A: B
