tolong dong jawabpin

[tex] \frac{7}{5 + 2 \sqrt{3} } \times \frac{5 - 2 \sqrt{3} }{5 - 2 \sqrt{3} } = \frac{7(5 - 2 \sqrt{3)} }{ {5}^{2} - {(2 \sqrt{3)} }^{2} } [/tex]

[tex] = \frac{35 - 14 \sqrt{3} }{25 - 4.3} [/tex]
[tex] = \frac{35 - 14 \sqrt{3} }{25 - 12} [/tex]
[tex] = \frac{35 - 14 \sqrt{3} }{13} [/tex]
