Which expression is equal to 6/sqrt(5) ?
\(\begin{array}{|rcll|} \hline && \dfrac{6}{\sqrt{5}} \\\\ &=& \dfrac{6}{\sqrt{5}}\cdot \dfrac{\sqrt{5}}{\sqrt{5}} \\\\ &=& \dfrac{6\sqrt{5}}{\sqrt{5}\sqrt{5}} \\\\ &=& \dfrac{6\sqrt{5}}{\sqrt{5\cdot 5}} \\\\ &=& \dfrac{6\sqrt{5}}{\sqrt{5^2}} \\\\ &=& \dfrac{6\sqrt{5}}{5} \\ \hline \end{array}\)
