zad 4
a) √8² + √36² = 8 +36 = 44
b) ∛27³ + ∛3³ = 27 + 3 = 30
c) (√28)² - (√16)² = 28 - 16 = 12
d) (∛9)³ - (∛19)³ = 9 - 19 = - 10
e) ∛1000² + √100³ = ∛(10³)² + √(10²)³ = ∛10⁶ + √10⁶ =
= ∛10³ * ∛10³ + √10² * √10² * √10² = 10 * 10 + 10 * 10 * 10 = 100 + 1000 = 1100
f) (√64)³ - ∛8² = 8³ - ∛64 = 512 - 4 = 508
