Rationalise the denominator of each of the following

SoLuTiOn

(I)

$\frac{1}{ \sqrt{7} }$

$\frac{1}{ \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} }$

$= \frac{ \sqrt{7} }{( \sqrt{7) {}^{3} } }$

$\frac{ \sqrt{7} }{7}$

(ll)

$\frac{ \sqrt{5} }{ \sqrt[2]{3} }$

$\times \frac{ \sqrt{3} }{ \sqrt{3} }$

$= \frac{ \sqrt{15} }{6}$
