pecaha 2√3-5/6+√3 dirasionalkan penyebutnya menjadi

[tex] = \frac{2 \sqrt{3} - 5}{6 + \sqrt{3} } \times \frac{6 - \sqrt{3} }{6 - \sqrt{3} } \\ = \frac{12 \sqrt{3} - 6 - 30 + 5 \sqrt{3} }{36 - 3} \\ = \frac{17 \sqrt{3} - 36}{ 33} \\ = \frac{17}{33} \sqrt{3} - \frac{12}{11} \\ = \frac{17}{33} \sqrt{3} - 1 \frac{1}{11} [/tex]
