Vì \(2012\times2013< 2012\times2013+1\)và \(2013>2012\)
\(\Rightarrow\)\(\frac{2012\times2013}{2012\times2013+1}< 1< \frac{2013}{2012}\)
\(\Rightarrow\)\(\frac{2012\times2013}{2012\times2013+1}< \frac{2013}{2012}\)
\(\Rightarrow\)\(A< B\)
Vậy \(A< B\)
Bn nào xem Sea Games 29 thì kb và tk nha !!!
=)) Thanks ✌️✌️✌️

ta có : \(\frac{2012\times2013}{2012\times2013}\)có giá trị = 1.nên A có giá trị bằng 2
ta thấy : B = 1,000497018 => A > B
nhớ k nhá

a: \(11^{14}< 11^{15}\)
b: \(4^{300}=64^{100}\)
\(3^{400}=81^{100}\)
mà 64<81
nên \(4^{300}< 3^{400}\)
