Answer: (D)

Verified step by step guidance

1. Identify the cube roots in the expression: \(\sqrt[3]{50} + \sqrt[3]{8} - \sqrt[3]{18}\).
2. Simplify any cube roots that are perfect cubes or can be factored to include a perfect cube. For example, \(\sqrt[3]{8}\) can be simplified because 8 is a perfect cube.
3. Express each radicand (the number inside the cube root) as a product of a perfect cube and another factor, if possible. For example, write 50 as \$25 \times 2\( and 18 as \)9 \times 2$.
4. Rewrite each cube root using the property \(\sqrt[3]{a \times b} = \sqrt[3]{a} \times \sqrt[3]{b}\), and simplify the cube roots of perfect cubes.
5. Combine like terms if possible. Since cube roots with different radicands cannot be combined directly, leave the expression in simplified radical form.
