[tex]\frac{\sqrt{3}}{4} -\frac{\sqrt{3}}{3} =\frac{3\sqrt{3}}{12} -\frac{4\sqrt{3}}{12} =\frac{3\sqrt{3}-4\sqrt{3}}{12}=\frac{-\sqrt{3}}{12}[/tex]
[tex]\frac{\sqrt{3}}{\sqrt{16}} - \frac{\sqrt{3}}{\sqrt{9}} = \frac{\sqrt{3}}{4} - \frac{\sqrt{3}}{3} = \frac{3\sqrt{3}-4\sqrt{3}}{12} = -\frac{\sqrt{3}}{12}[/tex]
