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 sánh:
a) A=\(\frac{2015^{2016}+1}{2015^{2017}+1}\)và B=\(\frac{2015^{2015}+1}{2015^{2016}+1}\)
so sánh A=\(\frac{2015^{2016}+1}{2015^{2017}+1}\) và B=\(\frac{2015^{2017}+1}{2015^{2018}+1}\)
So sánh
\(A=\frac{2015^{2015}+1}{2015^{2016}+1}\)và \(B=\frac{2015^{2016}+1}{2015^{2017}+1}\)
SO SÁNH:
A=\(\frac{\frac{2016}{1}+\frac{2015}{2}+\frac{2014}{3}+.....+\frac{2}{2015}+\frac{1}{2016}}{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+.....+\frac{1}{2016}+\frac{1}{2017}}\)
VÀ
B=2017
So sánh hai phân số : A=\(\frac{2015}{2016}+\frac{2016}{2017}+\frac{2017}{2018}\)và B=\(\frac{2015+2016+2017}{2016+2017+2018}\)
So sánh
\(A=\frac{2015^{2015}+1}{2015^{2016}+1}\)và \(B=\frac{2015^{2016}+1}{2015^{2017}+1}\)
nói cách làm nhé ^_^
So sánh :
\(\frac{2015^{2016}+1}{2015^{2017}+1}và\frac{2015^{2017}+1}{2015^{2018}+1}\)
So sánh 2 phân số sau\(\frac{2014+2015+2016}{2015+2016+2017}\) và \(\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)
