Odpowiedź:
a)
∛(28 + 4)/∛(13 - 9) = ∛32/∛4 = ∛(32/4) = ∛8 = 2
b)
8⁻⁵ * 4⁷ = (2³)⁻⁵ * (2²)⁷ = 2⁻¹⁵ * 2¹⁴ =2⁻¹⁵⁺¹⁴ =2⁻¹ = 1/2
c)
(⁴√9 * 27)⁴ = (9¹⁾⁴ * 3³)⁴ = (3²⁾⁴ * 3³)⁴ = (3¹⁾²)⁴ * (3³)⁴ = 3⁴⁾² * 3¹² =
= 3² * 3¹² = 3²⁺¹² = 3¹⁴ = 4782969
d)
(⁵√(- 32) * 2⁻¹)/4 * 2² = (- 2 * 2⁻¹)/4 * 2² = (- 2 * 1/2)/4 * 4 = - 2 * 1/2 = - 1
