Question 1 Report

Simplify \(\frac{1}{(1-\sqrt{3})^{2}}\)

Answer Details
We can simplify the given expression as follows: \begin{align*} \frac{1}{(1-\sqrt{3})^2} &= \frac{1}{1-2\sqrt{3}+3} \\ &= \frac{1}{4-2\sqrt{3}} \\ &= \frac{4+2\sqrt{3}}{(4-2\sqrt{3})(4+2\sqrt{3})} \\ &= \frac{4+2\sqrt{3}}{16-12} \\ &= \frac{4+2\sqrt{3}}{4} \\ &= 1 + \frac{1}{2}\sqrt{3} \end{align*} Therefore, the answer is (B) \(1+ \frac{1}{2}\sqrt{3}\).
