Question

2 + root 3
________
2-root 3

Answer 1

Answer:

$\frac{2 + \sqrt{2} }{2 - \sqrt{2} } = \\ \\ = > \frac{(2 + \sqrt{2)}(2 + \sqrt{2} ) }{(2 - \sqrt{2} )(2 + \sqrt{2} ) } \\ \\ \\ = > \frac{ {(2 + \sqrt{2} )}^{2} }{4 - 2} \\ \\ \\ \\ = > \frac{4 + 2 + 4 \sqrt{2} }{2} \\ \\ \\ = > \frac{6 + 4 \sqrt{2} }{2} \\ \\ \\ \\ = > \frac{2(3 + 2 \sqrt{2}) }{2} \\ \\ \\ = > 3 + 2 \sqrt{2} \\ \\ = > 3 + 2 \times 1.41 \\ \\ \\ = > 3 + 2.82 = 5.82$
