Answer 2

Answer:

We cannot Rationalize it because the numerator can contain a root, but the denominator should not. The final expression may look more complicated in its rational form, but that's what you have to do sometimes.

Rationalization should be done only when a root is present in the denominator.

Hence, it is already rationalized.
