Question

rationalize 1 upon root 7

Answer 1

Hello Friend !

The answer is given below :-

Given, $\frac{1}{ \sqrt{7} }$

Therefore for rationalising it multiply both the numerator and the denominator with the irrational number ,i.e., $\sqrt{7}$ in this case.

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

⇒  $\frac{ \sqrt{7}}{7}$

This is your answer .
