Enter your answer in the box.

Answer 1

`(√(77) )/(11)`

Explanation:

Using the rule of radicals

`√(a)` ×
`√(b)` ⇔
`√(ab)` and

`√(a)` ×
`√(a)` = a

Given

`(√(7) )/(√(11) )`

To rationalise the denominator multiply numerator/ denominator by
`√(11)`

`(√(7) )/(√(11) )` ×
`(√(11) )/(√(11) )`

=
`(√(7(11)) )/(√(11(11)) )`

=
`(√(77) )/(11)`
