Solution Steps

Step 1: Identify the radical expression

The given expression is \(\sqrt[3]{-216}\), which represents the cube root of \(-216\).

Step 2: Determine the cube root

To find the cube root of \(-216\), we look for a number \(x\) such that \(x^3 = -216\). Since \((-6)^3 = -6 \times -6 \times -6 = -216\), the cube root of \(-216\) is \(-6\).

Step 3: Write the final result

The cube root of \(-216\) is \(-6\), so \(\sqrt[3]{-216} = -6\).

Final Answer

\(\boxed{-6}\)
