What is the coefficient of (x^2y) in the term (5x^2y)?
Answer and explanation
Correct answer: 5
The term 5x^2y can be written as 5 \(\times x^2y\). Thus, the numerical factor multiplying \(x^2y\) is 5, so its coefficient is 5. The number 2 is the exponent of x in \(x^2\), not the coefficient. Exam tip: The number multiplying the stated algebraic part of a term is its coefficient.
