Gọi A = 2017/2018 + 2018/2017
= 2017-1/2018 + 2017+1/2017
= 1 - 1/2018 + 1 + 1/2017
= 2 + ( -1/2018 + 1/2017)
Từ trên => A> 2

Cho A= \(\frac{2017^{2018}+1}{2017^{2018}-3}\)
B= \(\frac{2017^{2018}-1}{2017^{2018}-5}\)
Hãy so sánh A với B
So sánh 2 biểu thức:
M = \(\frac{2016}{2017}\)+\(\frac{2017}{2018}\)+\(\frac{2018}{2019}\)
N = \(\frac{2016+2017+2018}{2017+2018+2019}\)
So sánh
M = \(\frac{2016}{2017}+\frac{2017}{2018}\&N\frac{2016+2017}{2017+2018}?\)
So sánh:
\(C=\frac{2018^{2019}-1}{2018^{2018}-1}\)và\(D=\frac{2017^{2018}+1}{2017^{2017}+1}\)
So sánh 2 phân số
A=\(\frac{2015}{2016}+\frac{2016}{2017}+\frac{2017}{2018}\)
B=\(\frac{2015+2016+2017}{2016+2017+2018}\)
So sánh \(\frac{2017}{2018}+\frac{2018}{2019}và\frac{2015}{2016}+\frac{2016}{2017}\)
SO SÁNH\(\frac{2016}{2017}\)+\(\frac{2017}{2018}\)VÀ \(\frac{2016+2017}{2017+2018}\)
so sánh A=\(\frac{2016^{2017}+1}{2017^{2018}+1}\)và B=\(\frac{2017^{2018}+1}{2017^{2017}+1}\)
Cho
A = \(\frac{2017^{2018}+1}{2017^{2018}-3}\)
B= \(\frac{2017^{2018}-1}{2017^{2018}-5}\)
So sánh A và B
