tolong ya kak di jawab no 1 dan 2.

[tex] = \frac{6}{ \sqrt{5} - \sqrt{2} } \\ = \frac{6}{ \sqrt{5} - \sqrt{2} } \times \frac{ \sqrt{5} + \sqrt{2} }{ \sqrt{5} + \sqrt{2} } \\ = \frac{6( \sqrt{5} + \sqrt{2} )}{5 - 2} \\ = \frac{6 (\sqrt{5} + \sqrt{2}) }{3} \\ = 2( \sqrt{5} + \sqrt{2} ) \\ = 2 \sqrt{5} + 2 \sqrt{2} [/tex]
