bentuk sederhana dari 12 per akar 5 kurang akar 2

[tex] = \frac{12}{ \sqrt{5} - \sqrt{2} } \times \frac{ \sqrt{5} + \sqrt{2} }{ \sqrt{5} + \sqrt{2} } \\ \\ = \frac{12 \sqrt{5} + 12 \sqrt{2} }{5 - 3} \\ \\ = \frac{12 \sqrt{5} + 12 \sqrt{2} }{3} \\ \\ = 4 \sqrt{5} + 4 \sqrt{2} \\ \\ = 4( \sqrt{5} + \sqrt{2} )[/tex]
