Answer 1

$\frac{\sqrt{ {( \frac{ \sqrt{3} }{3} - tg \frac{\pi}{3}) }^{2} } }{(ctg \frac{\pi}{6} - ctg \frac{\pi}{3}) } \\ \\ \frac{ \sqrt{ {( \frac{ \sqrt{3} }{3} - \sqrt{3}) }^{2} \times 2} }{(ctg \frac{\pi}{6} - ctg \frac{\pi}{3}) \times 2} \\ \\ \frac{ \sqrt{ {( \frac{ \sqrt{3} }{3} - \sqrt{3}) }^{2} } }{( \sqrt{3} - \frac{ \sqrt{3} }{3} )\times 2 } \\ \\ \\ \frac{ \sqrt{ {( - \frac{ 2\sqrt{3} }{3}) }^{2} } }{ \frac{2 \sqrt{3} }{3} \times 2} \\ \\ \frac{ \frac{2 \sqrt{3} }{3} }{ \frac{2 \sqrt{3} }{3} \times 2} = \frac{1}{2}$
