Ta có: \(12>9\)
\(6\sqrt{3}>4\sqrt{5}\)
Do đó: \(12+6\sqrt{3}>9+4\sqrt{5}\)
\(\Leftrightarrow\sqrt{12+6\sqrt{3}}>\sqrt{9+4\sqrt{5}}\)

Ta có :\(\frac{1}{\sqrt{1}}>\frac{1}{\sqrt{25}}\left(1\right);\frac{1}{\sqrt{2}}>\frac{1}{\sqrt{25}}\left(2\right);\frac{1}{\sqrt{3}}>\frac{1}{\sqrt{25}}\left(3\right);...;\frac{1}{\sqrt{24}}>\frac{1}{\sqrt{25}}\left(24\right);\frac{1}{\sqrt{25}}=\frac{1}{\sqrt{25}}\left(25\right)\)
Cộng các vế từ (1) -> (25),ta có :\(A>\frac{1}{\sqrt{25}}.25=\frac{25}{5}=5\)
P/S : Theo cách làm trên,ta có công thức tổng quát :\(\frac{1}{\sqrt{1}}+\frac{1}{\sqrt{2}}+\frac{1}{\sqrt{3}}+...+\frac{1}{\sqrt{n-1}}+\frac{1}{\sqrt{n}}>\sqrt{n}\left(n\in N;n>1\right)\)
Có \(\sqrt{8}\). 4 = \(\sqrt{\frac{128}{16}}\).4 > \(\sqrt{\frac{81}{16}}\).4 = 9/4 . 4 =9 = 3.3
<=> \(\frac{\sqrt{8}}{3}\)> 3/4
