merasionalkan bilangan akar 3 / akar 12 - akar 3

[tex] \frac{3}{ \sqrt{12} - \sqrt{3} } \\ = \frac{3}{ \sqrt{12} - \sqrt{3} } \times \frac{\sqrt{12} + \sqrt{3}}{\sqrt{12} + \sqrt{3}} \\ = \frac{3( \sqrt{12} + \sqrt{3)} }{12 - 3} \\ = \frac{3( \sqrt{12} + \sqrt{3)} }{9} \\ = \frac{\sqrt{12} + \sqrt{3} }{3}[/tex]
