Answer:

x =   \frac{ \sqrt{3}  +  \sqrt{2} }{ \sqrt{3}  -  \sqrt{2} }  \\ y =  \frac{ \sqrt{3}  -  \sqrt{2} }{ \sqrt{3}  +  \sqrt{2} }  \\ than \:  {x}^{2}  +  {y}^{2}  =  { \frac{( \sqrt{3} +  \sqrt{2} ) }{ {( \sqrt{3}  -  \sqrt{2} )}^{2}  } }^{2}  +  \frac{ {( \sqrt{3}  -  \sqrt{2}) }^{2} }{ {( \sqrt{3}  +  \sqrt{2} )}^{2} }  \\  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =  \frac{3 + 2 + 2 \sqrt{6} }{3 + 2 - 2 \sqrt{6} }  +  \frac{3 + 2 - 2 \sqrt{6} }{3 + 2 + 2 \sqrt{6} }  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{5 + 2 \sqrt{6} }{5 - 2 \sqrt{6} }  +  \frac{5  - 2 \sqrt{6} }{5 + 2 \sqrt{6} }  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{5 + 2 \sqrt{6}  + 5 - 2 \sqrt{6} }{ {(5)}^{2} -  {(2 \sqrt{6)} }^{2}  }  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{10}{25 - 24}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 10 \:  \:  \: ans.
