Question

so sanh

A=\(\frac{2016^{2016}+1}{2016^{2017}+1}\)

B=\(\frac{2016^{2017}-3}{2016^{2018}-3}\)

Answer 1

\(A=\frac{2016^{2016}+1}{2016^{2017}+1}\Rightarrow2016A=\frac{2016^{2017}+2016}{2016^{2017}+1}=1+\frac{2015}{2016^{2017}+1}\)

\(B=\frac{2016^{2017}-3}{2016^{2018}-3}\Rightarrow2016B=\frac{2016^{2018}-6048}{2016^{2018}-3}=1+\frac{-6045}{2016^{2018}-3}\)

Vì \(\frac{2015}{2016^{2017}+1}>0;\frac{-6045}{2016^{2018}-3}< 0\)

Nên: A>B

Answer 2

cho mk hoi con cach giai nao khac ko z??

Answer 3

2016A=\(\frac{2016^{2017}+2016}{2016^{2017}+1}\Rightarrow1+\frac{2016}{2016^{2017}+1}\)

2016B=\(\frac{2016^{2018}-2016}{2016^{2018}-3}\Rightarrow1-\frac{2016}{2016^{2018}-3}\)

\(\Rightarrow\)2016A>2016B\(\Rightarrow\)A>B
