 \frac{ \sqrt{11}  +  \sqrt{5} }{ \sqrt{11}   -  \sqrt{5} }  \\  =  \frac{( \sqrt{11} +  \sqrt{5})( \sqrt{11}  +  \sqrt{5}  ) }{( \sqrt{11} -  \sqrt{5} )( \sqrt{11}  +  \sqrt{5} ) }  \\  =  \frac{( \sqrt{11}  +  \sqrt{5}) {}^{2}  }{ { \sqrt{11} }^{2}  -  { \sqrt{5} }^{2} }   \\  =  \frac{11 + 5 + 2 \sqrt{55} }{11 - 5}  \\  =  \frac{16 + 2 \sqrt{55} }{6}  \\  =  \frac{8 +  \sqrt{55} }{3}
