It depends on what the denominator was to start with: a surd or irrational or a complex number.
You need to find the conjugate and multiply the numerator by this conjugate as well as the denominator by the conjugate. Since multiplication is by [conjugate over conjugate], which equals 1, the value is not affected.
If a and b are rational numbers, then
conjugate of sqrt(b) = sqrt(b)
conjugate of a + sqrt(b) = a - sqrt(b), and
conjugate of a + ib = a - ib where i is the imaginary square root of -1.
