    Answer:

     =  \frac{ - 5}{ \sqrt{3}  -  \sqrt{5} } \\  \\  =  \frac{ - 5}{ \sqrt{3}  -  \sqrt{5} }  \times  \frac{  \sqrt{3} +  \sqrt{5}  }{ \sqrt{3}   +   \sqrt{5} }  \\  \\  =  \frac{ - 5 \sqrt{3}  - 5 \sqrt{5} }{3 - 5}  \\  \\  =  \frac{ - (5 \sqrt{3} + 5 \sqrt{5}  )}{ - 2}  \\  \\  =  \frac{ 5 ( \sqrt{3} + \sqrt{5}  )}{  2}
