To simplify the expression 2 + √3, we can't combine the 2 and √3 because they are different types of terms (a constant and a radical). However, we can simplify the expression by rationalizing the denominator.

We can do this by multiplying the top and bottom of the fraction by the conjugate of the denominator, which is 2 - √3. This will give us:

(2 + √3) * (2 - √3) / (2 - √3)

Simplifying the numerator, we get:

(2 * 2) - (2 * √3) + (√3 * 2) - (√3 * √3)

= 4 - 3

= 1

So the expression simplifies to:

1 / (2 - √3)

To rationalize the denominator, we can multiply the top and bottom by the conjugate of the denominator again, which is 2 + √3. This gives us:

1 * (2 + √3) / ((2 - √3) * (2 + √3))

= (2 + √3) / (2^2 - (√3)^2)

= (2 + √3) / (4 - 3)

= 2 + √3

So the simplified form of 2 + √3 is 2 + √3.
