Answer 1

(a)

Explanation:

To rationalise the fraction multiply the numerator/denominator by the conjugate of the denominator.

The conjugate of
`√(3)` +
`√(x)` is
`√(3)` -
`√(x)`

Hence

`(√(9)(√(3)-√(x) )  )/((√(3)+√(x) )(√(3)-√(x) )  )`

=
`(3(√(3)-√(x)  )/(3-x)`

=
`(3√(3)-3√(x)  )/(3-x)` → (a)
