a) \(\sqrt{sin^5 \frac{\pi}{6} - 2sin^5 \frac{\pi}{6} \cdot sin \frac{\pi}{5} + sin^5 \frac{\pi}{5}} - \sqrt{sin^5 \frac{5\pi}{6} - 2sin^5 \frac{5\pi}{6} \cdot sin \frac{\pi}{5} + sin^5 \frac{\pi}{5}} = -1\)

б) \(\sqrt{cot^4 \frac{\pi}{3} - 2cot^4 \frac{\pi}{3} \cdot cos \frac{\pi}{3} + cos^4 \frac{\pi}{3}} + \sqrt{cos^4 \frac{\pi}{3} - 2cot^4 \frac{\pi}{3} \cdot cos \frac{\pi}{3} + cos^4 \frac{\pi}{3}} = -2084\)

Ответ: а) -1; б) -2084
