If x = 4, what is x cubed?

If x = 4, what is x cubed?

• A. 16
• B. 32
• C. 64
• D. 256

Answer: (C)

Cubing a number means multiplying it by itself three times: x^3 = x × x × x. With x = 4, you get 4 × 4 × 4. Multiply 4 by 4 to get 16, then multiply by 4 again to reach 64. So the result is 64. The other values come from different powers: 16 is x^2, 256 is x^4, and 32 isn’t a standard whole-number power of 4.
