What is \( \sqrt[3]{125} ? \)

Use \( <,> \), or \( = \) to compare the \( \begin{array}{cc}\begin{array}{ll}\text { (a) } 0.37 & \square 0.39 \\ \text { (b) } 6.4 & \square 6.40 \\ \text { (c) } 0.04 & \square 0.1\end{array} & \square<\square \\ \square>\square & \square=\square \\ \times & 5\end{array} \)
