rationalise the number 1/√7

Answer 1

Hola Mate!!

Your answer :-

Rationlizing the denominator =>

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

↪Hence, the denominator is rationalised. As, 7 is a rational number✔
