bentuk sederhana dari 2+4✓2/3+2✓2 adalah

[tex] \frac{2 + 4 \sqrt{2} }{3 + 2 \sqrt{2} } \\ =\frac{2 + 4 \sqrt{2} }{3 + 2 \sqrt{2}} \times \frac{3 - 2 \sqrt{2} }{3 - 2 \sqrt{2} } \\ = \frac{6 - 4 \sqrt{2} + 12 \sqrt{2} - 8 \times 2 }{9 - 6 \sqrt{2} + 6 \sqrt{2} - 4 \times 2 } \\ = \frac{6 - 8 \sqrt{2} - 16 }{9 - 8} \\ = - 8 \sqrt{2} - 10
