1. The problem is to simplify the expression $$\frac{4}{4 + \sqrt{14}}$$.
2. To simplify a fraction with a surd in the denominator, we multiply numerator and denominator by the conjugate of the denominator to rationalize it. The conjugate of $$4 + \sqrt{14}$$ is $$4 - \sqrt{14}$$.
3. Multiply numerator and denominator by $$4 - \sqrt{14}$$:
$$\frac{4}{4 + \sqrt{14}} \times \frac{4 - \sqrt{14}}{4 - \sqrt{14}} = \frac{4(4 - \sqrt{14})}{(4 + \sqrt{14})(4 - \sqrt{14})}$$
4. Simplify the denominator using the difference of squares formula:
$$ (4 + \sqrt{14})(4 - \sqrt{14}) = 4^2 - (\sqrt{14})^2 = 16 - 14 = 2 $$
5. So the expression becomes:
$$ \frac{4(4 - \sqrt{14})}{2} $$
6. Distribute the 4 in the numerator:
$$ \frac{16 - 4\sqrt{14}}{2} $$
7. Simplify the fraction by dividing numerator and denominator by 2:
$$ \frac{\cancel{16}^8 - \cancel{4}^2\sqrt{14}}{\cancel{2}^1} = 8 - 2\sqrt{14} $$
8. Therefore, the simplified form is $$8 - 2\sqrt{14}$$.
9. Comparing with the options, the answer is (b) $$8 - 2 \sqrt{14}$$.
