Kita selesaikan soal matematika ini langkah demi langkah:⸻Soal:\frac{3 + \sqrt{2}}{3 - \sqrt{2}} - \frac{4 - \sqrt{2}}{4 + \sqrt{2}}⸻✅ Langkah 1: Rasionalisasi pecahan pertama\frac{3 + \sqrt{2}}{3 - \sqrt{2}} \times \frac{3 + \sqrt{2}}{3 + \sqrt{2}} = \frac{(3 + \sqrt{2})^2}{3^2 - (\sqrt{2})^2} = \frac{9 + 6\sqrt{2} + 2}{9 - 2} = \frac{11 + 6\sqrt{2}}{7}⸻✅ Langkah 2: Rasionalisasi pecahan kedua\frac{4 - \sqrt{2}}{4 + \sqrt{2}} \times \frac{4 - \sqrt{2}}{4 - \sqrt{2}} = \frac{(4 - \sqrt{2})^2}{4^2 - (\sqrt{2})^2} = \frac{16 - 8\sqrt{2} + 2}{16 - 2} = \frac{18 - 8\sqrt{2}}{14}Sederhanakan:\frac{18 - 8\sqrt{2}}{14} = \frac{9 - 4\sqrt{2}}{7}⸻✅ Langkah 3: Kurangkan hasil\frac{11 + 6\sqrt{2}}{7} - \frac{9 - 4\sqrt{2}}{7} = \frac{(11 + 6\sqrt{2}) - (9 - 4\sqrt{2})}{7}Sederhanakan:= \frac{11 - 9 + 6\sqrt{2} + 4\sqrt{2}}{7} = \frac{2 + 10\sqrt{2}}{7}⸻✅ Jawaban akhir:\boxed{\frac{2 + 10\sqrt{2}}{7}}
