Odpowiedź:
√49 - ∛-27 = √7² - ∛(-3)³ = 7 - (-3) = 7 + 3 = 10
5√1/100 + √121/4 = 5√1²/10² + √11²/4 = 5×1/10 + 11/4 = 1/2 + 2 3/4 =
= 2/4 + 2 3/4 = 2 5/4 = 3 1/4
∛(36×√36) = ∛( 6²×√6²) = ∛( 6²×6) = ∛6³ = 6
√[3√(3√9)] = √[3√(3×3)] = √[3√9] = √(3×3) = √9 = √3² = 3
√16 + √9 - √(16+9) = √4² + √3² - √25 = 4 + 3 - √5² = 7 - 5 = 2
√400 ÷ ∛8 + √25 = √20² ÷ ∛2³ + √5² = 20 ÷ 2 + 5 = 10 +5 = 15
