Question

Calcule as raízes:
B) √49/144
C)³√64
D)³√27/125

Answer 1

B) √(49/144)  ------ 7/12

C) ∛64 ------ 4

D) ∛(27/125) ----- 3/5

Answer 2

B) $\sqrt{ \frac{49}{144} } = \sqrt{( \frac{7}{12} )^{2} } = \frac{7}{12}$

C) $\sqrt[3]{64} = \sqrt[3]{4^{3} } = 4$

D) $\sqrt[3]{ \frac{27}{125} } = \sqrt[3]{( \frac{3}{5} )^{3} } = \frac{3}{5}$
