Решение:

  1. \(\sqrt{4^3} = \sqrt{4^2 \cdot 4} = 4\sqrt{4} = 4 \cdot 2 = 8\)
  2. \(\sqrt{9^5} = \sqrt{9^4 \cdot 9} = 9^2 \sqrt{9} = 81 \cdot 3 = 243\)
  3. \(\sqrt{4^5} = \sqrt{4^4 \cdot 4} = 4^2 \sqrt{4} = 16 \cdot 2 = 32\)
  4. \(\sqrt{16^3} = \sqrt{16^2 \cdot 16} = 16 \sqrt{16} = 16 \cdot 4 = 64\)
  5. \(\sqrt{25^3} = \sqrt{25^2 \cdot 25} = 25 \sqrt{25} = 25 \cdot 5 = 125\)

Ответ: 2.1. 8, 2.2. 243, 2.3. 32, 2.4. 64, 2.5. 125.
