Given :

➠ \:  \frac{1}{ {7} +  \sqrt{3}  }

Solution :

 ➠ \: \frac{1}{7 +  \sqrt{3} }

➠ \:  \frac{1}{7 +  \sqrt{3} }  \times   \frac{7 -  \sqrt{3} }{7 -  \sqrt{3} }

• We use the identity [ (a+b) (a-√b) = a² - b ]

➠ \:  \frac{7 - \sqrt{3}  }{49 - 3}  =  \frac{7 -  \sqrt{3} }{46}

➠ \: { \sf{Answer \:  is =  { \boxed{ \blue{ \sf{\frac{7 -  \sqrt{3} }{46}}}}}}} \star

_________________________

• So, when the denominator of an expression contains a term with a square root (or a number under radical sign), the process of converting it to an equivalent expression whose denominator is a rational number is called rationalising the denominator.
