Which of the following is the numerical coefficient of x²y²?

  • A.1
  • B.x²
  • C.y²

Answer: A

The numerical coefficient is the number multiplying the variable part. Written in full, the term is

\[ x^{2}y^{2} = 1 \cdot x^{2}y^{2} \]

so the coefficient is 1. \( x^{2} \) and \( y^{2} \) are parts of the variable factor, not numbers.
