C.

Explanation:

Answer 2

Choice c is the answer.

Explanation:

We have given a expression.

`(√(x) )/(√(x)+√(5))`

We have to find the rationalized form of above expression.

Multiplying and dividing by
`√(x)-√(5)` to given expression,we have

`(√(x) )/(√(x)+√(5)  ) (√(x)-√(5)  )/(√(x)-√(5)  )`

`(√(x)(√(x)-√(5)))/((√(x))^(2)-(√(5))^(2))`

`((√(x))^(2)-√(5)√(x))/(x-5)`

`(x-√(5x) )/(x-5)` which is the rationalized form of given expression.
