[tex] \sqrt{a \times b} [/tex]
[tex] \sqrt{6} + \frac{12}{ \sqrt{6} } = \frac{6 + 12}{ \sqrt{6} } = \frac{18}{ \sqrt{6} } \\ \sqrt{54} - \sqrt{6} = \sqrt{9 \times 6} - \sqrt{6} = \\ 3 \sqrt{6} - \sqrt{6} = 2 \sqrt{6} [/tex]
[tex] \sqrt{a \times b} = \sqrt{ \frac{18}{ \sqrt{6} } \times 2 \sqrt{6} } = \sqrt{36} = 6[/tex]
