rasionalkan lah pangkat dari 3 per akar 11 dikurang akar 2

[tex] = \frac{3}{ \sqrt{11} - \sqrt{2} } \\ = \frac{3}{ \sqrt{11} - \sqrt{2} } \times \frac{ \sqrt{11} + \sqrt{2} }{ \sqrt{11} + \sqrt{2} } \\ = \frac{3 \sqrt{11} + \sqrt{3 \sqrt{2} } }{11 - 2} \\ = \frac{3 \sqrt{11} + 3 \sqrt{2} }{9} \\ = \frac{1}{3} ( \sqrt{11} + \sqrt{2} )[/tex]
