Вычислите: 2) \(\sqrt[3]{3^{12}}\); 3) \(\sqrt[4]{\left(\frac{1}{2}\right)^{12}}\); 4) \(\sqrt[4]{\left(\frac{1}{3}\right)^{16}}\).

1. \(\sqrt[3]{3^{12}}=3^{12/3}=3^4=81\).
2. \(\sqrt[4]{\left(\frac{1}{2}\right)^{12}}=\left(\frac{1}{2}\right)^{12/4}=\frac{1}{8}\).
3. \(\sqrt[4]{\left(\frac{1}{3}\right)^{16}}=\left(\frac{1}{3}\right)^{16/4}=\frac{1}{81}\).

Ответ: 2) 81; 3) \(\frac{1}{8}\); 4) \(\frac{1}{81}\).
