Math Problem Statement
Solve the equation
Solution
The question asks to rewrite the irrational cube root as a product of an integer and another irrational cube root.
Step-by-Step Solution:
-
Expression Analysis: We are working with . Since is negative, its cube root will also be negative. Let's factorize :
-
Cube Root Separation: Using the property of cube roots, : [ \sqrt[3]{-24} = \sqrt[3]{-8} \cdot \sqrt[3]{3} ]
-
Simplify the Cube Root of : The cube root of is because:
-
Final Answer: Substituting back: [ \sqrt[3]{-24} = -2 \cdot \sqrt[3]{3} ]
Thus, the correct answer is:
