$\frac{\sqrt 3}{\sqrt 3}$
Rationalizing the denominator involves multiplying both the numerator and the denominator of the fraction with a term that is the same as the denominator in order to remove the radical in the denominator. Therefore, to rationalize the denominator of $\frac{5}{\sqrt 3}$, we multiply by $\frac{\sqrt 3}{\sqrt 3}$.
