( [tex](5 \sqrt{2} - \sqrt{6} )(2 \sqrt{2} + 3 \sqrt{6} )[/tex] Tolong diisi ya ka

[tex] = 10 \sqrt{4} + 15 \sqrt{12} - 2 \sqrt{12} - 3 \sqrt{36} \\ = 10.2 + 13 \sqrt{12} - 3.6 \\ = 20 + 13 \sqrt{12} - 18 \\ = 2 + 13\sqrt{12} \\ = 2 + (13 \sqrt{4} \times \sqrt{3} ) \\ = 2 + (13.2 \sqrt{3} ) \\ = 2 + 26 \sqrt{3} \\ = 2 ( 1 + 13 \sqrt{3}) [/tex]
Semoga bermanfaat.....
