Buna! Cum calculez radicali in genul asta... (poza)

[tex]10^3 = 1000 \\ 9^3 = 729 \\ \\ \Rightarrow 10 = \sqrt[3]{1000} \\ \Rightarrow 9 = \sqrt[3]{729}\\ \\ \sqrt[3]{729} < \sqrt[3]{961} <\sqrt[3]{1000} \\ \\ 9 < \sqrt[3]{961}< 10 \Big|\cdot (-1) \\ \\ -9 > -\sqrt[3]{961}> -10 \\ \\ \Rightarrow \boxed{-10<\sqrt[3]{961}<-9}[/tex]
