Question :

 \blue \bigstar \large \rm \: rationalize \: the \: denominator \:   \\  \frac{14}{15 \sqrt{3}  -  \sqrt{5} }

Answer :

  \\ \implies \large \bf \:  \frac{14}{15 \sqrt{3}  -  \sqrt{5} }

 \\  \implies \large \bf \:  \frac{14}{ 15 \sqrt{3} -  \sqrt{5}  }  \times  \frac{15 \sqrt{3} +  \sqrt{5}  }{15 \sqrt{3}  +  \sqrt{5} }

 \\  \implies \large \bf \:  \frac{14(15 \sqrt{3}  +  \sqrt{5}) }{225 \times 3 - 5}

  \\ \implies \large \bf \:  \frac{14(15 \sqrt{3} +  \sqrt{5}  )}{675 - 5}

  \\ \implies \large \bf \:  \frac{14(15 \sqrt{3} +  \sqrt{5} ) }{670}

 \\  \implies \large \bf \:  \frac{7(15 \sqrt{3} +  \sqrt{5} ) }{335}

 \:  \red \bigstar \large \boxed{ \frac{7(15 \sqrt{3}  +  \sqrt{5}) }{355} } \:  \:  \sf \: is \: the \: answer
