To rationalize the denominator of the expression \(\frac{\sqrt{11}}{\sqrt{3}}\), you can multiply the numerator and denominator by \(\sqrt{3}\):
\[ \frac{\sqrt{11}}{\sqrt{3}} \cdot \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{11} \cdot \sqrt{3}}{\sqrt{3} \cdot \sqrt{3}} = \frac{\sqrt{33}}{3} \]
So, the simplified expression is:
\[ \frac{\sqrt{33}}{3} \]
