Answer 1

SOLUTION

TO DETERMINE

To Rationalize the denominator

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

EVALUATION

Here the given number is

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

Denominator = √7

Multiplying numerator and denominator both by √7 we get

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

$= \displaystyle \sf{ \frac{ \sqrt{7} }{ \sqrt{7} \times \sqrt{7} } }$

$= \displaystyle \sf{ \frac{ \sqrt{7} }{ {( \sqrt{7} ) }^{2} } }$

$= \displaystyle \sf{ \frac{ \sqrt{7} }{7 } }$

FINAL ANSWER

$\displaystyle \sf{ \frac{1}{ \sqrt{7} } = \frac{ \sqrt{7} }{7} }$
