Answer 2

Answer:

$\frac{5 \sqrt{2} + 2 \sqrt{3} }{5 \sqrt{2} - 2 \sqrt{3} }$

$\frac{5 \sqrt{2} + 2 \sqrt{3} }{5 \sqrt{2} - 2 \sqrt{3} } \times \frac{5 \sqrt{2} + 2 \sqrt{3} }{5 \sqrt{2} + 2 \sqrt{3} }$

$\frac{(5 \sqrt{2} + 2 \sqrt{3} ) {}^{2} }{(5 \sqrt{2}) {}^{2} - (2 \sqrt{3} ) {}^{2} }$

$\frac{(5 \sqrt{2}) {}^{2} + (2 \sqrt{3}) {}^{2} + 2(5 \sqrt{2} )(2 \sqrt{3} )}{50 - 12}$

$\frac{50 + 12 +20 \sqrt{6} }{38}$

$\frac{62 + 20 \sqrt{6} }{38}$

$\frac{2(31 + 10 \sqrt{6}) }{38}$

$\frac{31 + 10 \sqrt{6} }{19}$
