    Evaluate, \[\sqrt{\frac{4}{3}}-\sqrt{\frac{3}{4}}.\]

    A)  \[\frac{1}{2\sqrt{3}}\]                                  

    B)                         \[-\frac{1}{2\sqrt{3}}\]                

    C)                         \[1\]                                    

    D)                         \[\frac{5\sqrt{3}}{6}\]                  

    Correct Answer: A

    Solution :

    \[\frac{\sqrt{4}}{\sqrt{3}}-\frac{\sqrt{3}}{\sqrt{4}}=\frac{2}{\sqrt{3}}-\frac{\sqrt{3}}{2}\] \[=\frac{4-3}{2\sqrt{3}}=\frac{1}{2\sqrt{3}}\]
