2012*2012-2014*2010
=(2014 - 2010)x 2012
= 4 x 2012
=8048
2012*2012-2014*2010

Không tính cụ thể , hãy sắp xếp các biểu thức sau theo thứ tự giảm dần :
\(\frac{\frac{2010}{2011}}{\frac{2012}{2013}}+\frac{\frac{2011}{2012}}{\frac{2013}{2014}}+\frac{\frac{2012}{2013}}{\frac{2014}{2015}}\)
\(\frac{\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2013}}{\frac{2012}{2013}+\frac{2013}{2014}+\frac{2014}{2015}}\)
\(\frac{\frac{2010+2011+2012}{2011+2012+2013}}{\frac{2012+2013+2014}{2013+2014+2015}}\)
\(\frac{\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2013}}{\frac{2012+2013+2014}{2013+2014+2015}}\)
\(\frac{\frac{2010+2011+2012}{2011+2012+2013}}{\frac{2012}{2013}+\frac{2013}{2014}+\frac{2014}{2015}}\)
Cho A=2010+2011*2012;B=2012*20123-2014 .Tính A/B
Cho A=2010+2011*2012;B=2012*2013-2014.Tính A/B
Cho A=2010+2011*2012;B=2012*2013-2014 .Tính A/B.
Cho A = 2010+ 2011 x 2012 ; B = 2012 x 2013 – 2014
Tính A: B
Cho A = 2010+ 2011 x 2012 ; B = 2012 x 2013 – 2014
Tính A: B
(6/2008*2010+6/2010*2012+6/2012*2014+6/2014*2016+6/2016*2018)+3/x=3/2008
Tính A : B, biết :
A = 2010+2011 x 2012
B = 2012 x 2013 - 2014
Tính nhanh
\(\frac{2014+\frac{2013}{2}+\frac{2012}{3}+\frac{2011}{4}+\frac{2010}{5}+...+\frac{2}{2013}+\frac{1}{2014}}{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+...+\frac{1}{2012}+\frac{1}{2013}+\frac{1}{2014}}\)
Giải tự luận hộ mình nha!!!!!!!! Mình cảm ơn!!!
