What is the cube root of 64?

• A. 2
• B. 4
• C. 6
• D. 8

Answer: (B)

To find the cube root of 64, we need to determine which number, when multiplied by itself three times, gives us 64. The cube root is denoted as \( \sqrt[3]{64} \). Let's consider the calculation: 1. \( 2 \times 2 \times 2 = 8 \) (This means 2 is the cube root of 8, not 64.) 2. \( 3 \times 3 \times 3 = 27 \) (This means 3 is the cube root of 27, also not relevant here.) 3. \( 4 \times 4 \times 4 = 64 \) Since \( 4 \times 4 \times 4 \) equals 64, this tells us that the cube root of 64 is indeed 4. Therefore, the correct answer is based on the fundamental definition of cube roots and involves recognizing the relationship between the numbers and their cubes. In summary, for the number \( 4 \), it can be cubed to yield 64, confirming that it is the correct cube root value.

To find the cube root of 64, we need to determine which number, when multiplied by itself three times, gives us 64. The cube root is denoted as ( \sqrt[3]{64} ).

Let's consider the calculation:

1. ( 2 \times 2 \times 2 = 8 ) (This means 2 is the cube root of 8, not 64.)

2. ( 3 \times 3 \times 3 = 27 ) (This means 3 is the cube root of 27, also not relevant here.)

3. ( 4 \times 4 \times 4 = 64 )

Since ( 4 \times 4 \times 4 ) equals 64, this tells us that the cube root of 64 is indeed 4. Therefore, the correct answer is based on the fundamental definition of cube roots and involves recognizing the relationship between the numbers and their cubes.

In summary, for the number ( 4 ), it can be cubed to yield 64, confirming that it is the correct cube root value.
