Jawabannya adalah C. (3/2)(√11 + √3)
[tex] \frac{12}{ \sqrt{11} - \sqrt{3} } = \frac{12}{ \sqrt{11} - \sqrt{3} } \times \frac{ \sqrt{11} + \sqrt{3} }{ \sqrt{11} + \sqrt{3} } \\ = \frac{12( \sqrt{11} + \sqrt{3} )}{(11 + \sqrt{33} - \sqrt{33} - 3)} \\ = \frac{12( \sqrt{11} + \sqrt{3} )}{8} \\ = \frac{3( \sqrt{11} + \sqrt{3} )}{2} \\ = \frac{3}{2} ( \sqrt{11} + \sqrt{3} )[/tex]
