Penjelasan dengan langkah-langkah:
Rasionalkan saja. Pertama kita pindah ruas dulu:
16. [tex]p = \frac{78}{5\sqrt{2}+\sqrt{6} } \times \frac{5\sqrt{2}-\sqrt{6} }{5\sqrt{2}-\sqrt{6} }\\\\p = \frac{78(5\sqrt{2}-\sqrt{6} )}{50-6}= \frac{39(5\sqrt{2}-\sqrt{6} )}{22}[/tex]
17. Luas = s*s[tex](4\sqrt{3}+2 )\times (4\sqrt{3}+2) \\48+8\sqrt{3}+8\sqrt{3} +4\\ 52+16\sqrt{3} \ cm[/tex]
