 \frac{7 +  \sqrt{3} }{7 -  \sqrt{3} }  \\  =  \frac{7 +  \sqrt{3} }{7 -  \sqrt{3} }  \times  \frac{7 +  \sqrt{3} }{7 +  \sqrt{3} }  \\  =  \frac{( {7 +  \sqrt{3} )}^{2} }{ {7}^{2} - 3 }  \\  =  \frac{49 + 14 \sqrt{3} + 3 }{49 - 3}  \\  =  \frac{52 + 14 \sqrt{3} }{46}  \\  =  \frac{2(26 + 7 \sqrt{3} )}{46}  \\  =  \frac{26 + 7 \sqrt{3} }{23}

Hope it helps you.. plz mark it as Brainliest answer.. thanks
