As Per Given

  =  > \frac{14}{5 \sqrt{3}  -  \sqrt{5} } \\ \\  =  >  \frac{14}{5 \sqrt{3} -  \sqrt{5}  }  \times  \frac{5 \sqrt{3} +  \sqrt{5}  }{5 \sqrt{3}  +  \sqrt{5} } \\ \\  =  >  \frac{14(5 \sqrt{3} +  \sqrt{5}  )}{(5 \sqrt{3}) {}^{2}  - ( { \sqrt{5} })^{2}  } \\ \\  =  >  \frac{70 \sqrt{3}  + 14 \sqrt{5} }{75 - 5} \\ \\  =  >  \frac{70 \sqrt{3}  + 14 \sqrt{5} }{70} \\ \\  =  >  \frac{7(10 \sqrt{3}  + 2 \sqrt{5} )}{70} \\ \\  =  >  \frac{10 \sqrt{3} + 2 \sqrt{5}  }{10}  \\  \\ or \\  \\  =  >  \sqrt{3}  + 0.2 \sqrt{5}
