Answer 2

Jawaban:

[tex]15 + 4 \sqrt{14} [/tex]

Penjelasan dengan langkah-langkah:

[tex] \frac{2 \sqrt{2} + \sqrt{7} }{2 \sqrt{2} - \sqrt{7} } [/tex]

[tex] = \frac{2 \sqrt{2} + \sqrt{7} }{2 \sqrt{2} - \sqrt{7} } \times \frac{2 \sqrt{2} + \sqrt{7} }{2 \sqrt{2} + \sqrt{7} } [/tex]

[tex] = \frac{(4) \times (2) + 2 \sqrt{14} + 2 \sqrt{14} + 7 }{(4)(2) - 7} [/tex]

[tex] = \frac{8 + 4 \sqrt{14} + 7}{8 - 7} [/tex]

[tex] = 15 + 4 \sqrt{14}[/tex]
