[tex] \frac{10}{ \sqrt{3 - \sqrt{3} } } [/tex]

kukerjan penyebutnya dulu
√(3-√3) = √1/6 (3-√3)² + 1
            = (3-√3) √7/6
            = 3√7/6 - √21/6

10/√(3-√3) = 10 / (3√7/6 - √21/6)
                             10                 3√7/6 + √21/6     10 (3√7/6 + √21/6)
                  = --------------------- x ------------------- = ---------------------------
                     3√7/6 - √21/6        3√7/6 + √21/6            21/2 - 7/2
                                                                     
                                                                          = 10/7(3√7/6 + √21/6)
