What is the cube root of 27?

• A. 2
• B. 4
• C. 3
• D. 9

Answer: (C)

The cube root of a number is a value that, when multiplied by itself three times, gives the original number. In the case of 27, we are looking for a number that satisfies the equation \( x^3 = 27 \). To find this, consider the number 3. When you multiply 3 by itself three times, you have: \( 3 \times 3 \times 3 = 9 \times 3 = 27 \). This confirms that 3 is indeed the cube root of 27, as it meets the requirement of yielding the original number when cubed. Therefore, the answer is 3, affirming the reasoning behind the correct choice. Understanding this concept of cube roots is fundamental in arithmetic, as it allows one to relate various powers and understand their implications in different contexts.
