Find the cube root of (-1000000)

$$\begin{gathered} \mathrm{We} \mathrm{know} \mathrm{that} \sqrt[3]{1000000}=-\sqrt[3]{1000000} \\ 1000000=2\times 2\times 2\times 2\times 2\times 2\times 5\times 5\times 5\times 5\times 5\times 5 \\ \sqrt[3]{1000000}=2\times 2\times 5\times 5=100 \\ \sqrt[3]{1000000}=-100 \end{gathered}$$
