So sánh:\(\frac{37^{38}+5}{37^{39}+5}\) và \(\frac{37^{37}+1}{37^{38}+1}\)
Tính:\(\frac{2013}{2014}\cdot\frac{1006}{2015}+\frac{1009}{2014}\cdot\frac{2013}{2015}\)
so sanh a= 2015^2014+1/2015^2014-1 va b= 2015^2014-1/2015^2014-3
so sanh N=-7/(10^2014)+[-15/(10^2015)] va M=-15/(10^2014)+[-7/(10^2015)
so sanh (20^2015+11^2015)^2016 va (20^2016+11^2016)^2015
2015/-2014 va -2016/2015 . So sanh]
So sánh: a> A= 2015+2016 / 2016+2017 và B= 2015 / 2016 + 2016 / 2017
b> M=2015^35+1 / 2015^34+1 va N= 2015^34+1 / 2015^33+1
c> P= 2015^99+5 / 2015^99-1 va Q= 2015^99 +1 /2015^99
So sanh
A=2015^2015 + 1/ 2016^2016 + 1
B=2015^2014 + 1/ 2015^2015 + 1
A=(1+1/2015)×(1+1/2015^2)+...+(1+1/2015^2016)
So sanh voi B=2015^2-1/2014^2-1
