To rationalize the expression 2/√a + √x, we can multiply the numerator and denominator by the conjugate of the denominator, which in this case is √a:

(2/√a + √x) * (√a/√a)

This simplifies to:

(2√a + √a√x) / a

Then we can simplify further by combining like terms:

(2√a + √ax) / a

Therefore, the expression 2/√a + √x can be rationalized to (2√a + √ax) / a.
