so sánh P và Q biết : P= 2014/2015 + 2015/2016 + 2016/2017 và Q = 2014 + 2015 +2016/ 2015 +2016 + 2017

so sánh

(2016/2017)/(2017/2016) và (2014/2015)/(2015/2014)

1) CMR : A=(n+2015)(n+2016) + n² + n chia hết cho 2 với n ϵ N

2) So sánh :

       P = \(\frac{2013}{2014^{2013}}+\frac{2014}{2015^{2014}}+\frac{2015}{2016^{2015}}+\frac{2016}{2017^{2016}}\)  và 

       Q = \(\frac{2014}{2017^{2016}}+\frac{2013}{2016^{2015}}+\frac{2016}{2015^{2014}}+\frac{2015}{2014^{2013}}\)

Tinh A= 2014/2015+2015/2016+2016/2017+2017/2014 hay so sanh A voi 4

So sánh 2 phân số sau\(\frac{2014+2015+2016}{2015+2016+2017}\) và \(\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)

So sánh M và N biết:

M=\(\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)

N=\(\frac{2014+2015+2016}{2015+2016+2017}\)

evaluate the follwing:A= 2015 +2016 +2017/ 2014+2015+2016+2017+2018

so sánh P và Q

\(P=\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)

\(Q=\frac{2014+2015+2016}{2015+2016+2017}\)

Chứng minh

\(Â=\dfrac{2013}{2013+2014}+\dfrac{2014}{2014+2015}+\dfrac{2015}{2015+2016}+\dfrac{2016}{2016+2017}< 2\)
