3) \(\frac{\sqrt[4]{1024}}{\sqrt[4]{\pi}} ; 4) 5tg\(\frac{\pi}{4}\) - 6cos\(\frac{\pi}{3}\);

Решение:

1. \(\frac{\sqrt[4]{1024}}{\sqrt[4]{\pi}} = \sqrt[4]{\frac{1024}{\pi}} \)
2. \( 5\text{tg}\frac{\pi}{4} - 6\cos\frac{\pi}{3} = 5 \cdot 1 - 6 \cdot \frac{1}{2} = 5 - 3 = 2 \)

Ответ: 1) \( \sqrt[4]{\frac{1024}{\pi}} \); 2) 2.
