Here are the essential concepts you must grasp in order to answer the question correctly.
Cube Root
The cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of -8 is -2, since (-2) × (-2) × (-2) = -8. Understanding cube roots is essential for simplifying expressions involving cubic terms.

Negative Numbers and Odd Roots
When dealing with odd roots, such as cube roots, negative numbers can yield negative results. This is different from even roots, where the result is always non-negative. Recognizing this property is crucial for correctly simplifying expressions that include negative values.

Absolute Value
Absolute value represents the distance of a number from zero on the number line, regardless of direction. It is denoted by vertical bars, e.g., |x|. In the context of cube roots, absolute value may be necessary to express the non-negative result of an operation, especially when simplifying expressions that involve negative inputs.
