Question

Help me to do thjs two question

Answer 1

heyy dear user!!


solution:

ii)
$= > \frac{3 - 2 \sqrt{2} }{3 + 2 \sqrt{2} } \times \frac{3 - 2 \sqrt{2} }{3 - 2 \sqrt{2} } \\ = > \frac{{(3 - 2 \sqrt{2)} }^{2} }{ {3}^{2} - {(2 \sqrt{2)} }^{2} } \\ \\ = > \frac{9 + 8 - 12 \sqrt{2} }{9 - 8} \\ \\ = > 17 - 12 \sqrt{2}$
and


iii)
$= > \frac{5 - 3 \sqrt{14} }{7 + 2 \sqrt{14} } \times \frac{7 - 2 \sqrt{14} }{7 - 2 \sqrt{14} } \\ \\ = > \frac{35 - 10 \sqrt{14} - 21 \sqrt{14 } + 84}{49 - 56} \\ = > \frac{119 - 31 \sqrt{14} }{ - 7}$


hope it help u✌
