[tex] \sqrt{3} \times \sqrt{12} = \sqrt{36} = 6[/tex]
[tex] \sqrt{2} \times \sqrt{8} = 4[/tex]
[tex] \sqrt{7} \times \sqrt{21} = 7 \times \sqrt{3} [/tex]
[tex] \sqrt{5} \times \sqrt{10} = 5 \sqrt{2} [/tex]
[tex] \frac{ \sqrt{20} }{ \sqrt{5} } = 2[/tex]
[tex] \frac{ \sqrt{15} }{ \sqrt{5} } = \sqrt{3} [/tex]
[tex] \frac{ \sqrt{96} }{ \sqrt{6} } = 4[/tex]
[tex] \frac{ \sqrt{18} }{ \sqrt{3} } = \sqrt{6} [/tex]
