Rationalize the denominator.
 \frac{1}{3-√8} <br />Multiply 3+√8 both in numerator and denominators
We get,
  \frac{3+√8}{(3-√8)(3+√8}<br />
(3+√8)/9-8= 3+√8




 \frac{1}{5+2√3}<br /><br />
Multiply 1/5-2√3 both in numerator and denominator we have,
  \frac{5-2√3}{(5+2√3)(5-2√3)}<br /><br />
We get (5-2√3)/25-12= 5-2√3/13
