Ué, basta ir multiplicando:
[tex]1 \cdot 1 \cdot 1 = 1 \ \ \therefore \ \sqrt[3]{1} = 1
\\\\
2 \cdot 2 \cdot 2 = 8 \ \ \therefore \ \sqrt[3]{8} = 2
\\\\
3 \cdot 3 \cdot 3 = 27 \ \ \therefore \ \sqrt[3]{27} = 3
\\\\
4 \cdot 4 \cdot 4 = 64 \ \ \therefore \ \sqrt[3]{64} = 4
\\\\
5 \cdot 5 \cdot 5 = 125 \ \ \therefore \ \sqrt[3]{125} \rightarrow passamos \ do \ 100[/tex]
Era isso que queria?
