Ответ:

  1. √0,25 = √(1/4) = 1/2.
  2. ⁵√32 = 2, так как 2⁵ = 32.
  3. ∛(−3 3/8) = ∛(−27/8) = −3/2.
  4. 0,7·⁴√81 = 0,7·3 = 2,1.
  5. ⁴√(16/81)+∛(−1/8) = 2/3−1/2 = 1/6.
  6. (2∛4)³ = 2³·(∛4)³ = 8·4 = 32.
  7. 6/(2√3)² = 6/12 = 1/2.
  8. −²⁵√((-7)⁵) = −(−7)^(1/5) = ⁵√7.
  9. ⁴√16·∛(−125) = 2·(−5) = −10.
  10. ⁴√1·∛0,008 = 1·0,2 = 0,2.
  11. ⁴√2·⁴√8 = ⁴√16 = 2.
  12. ∛54·∛32 = ∛1728 = 12.
  13. ∛189/(3∛7) = (3∛7)/(3∛7) = 1.
  14. (2^(12/5)·2^(8/5))^(1/2) = (2⁴)^(1/2) = 4.
