What is the numerical coefficient in the term (11xy)?
Answer and explanation
Correct answer: 11
The numerical coefficient is the number multiplying the variables in a term. Since 11xy = 11 × x × y, its numerical coefficient is 11. Here, xy is the variable part; 1 would be the coefficient only if no number were written, as in xy. Exam tip: write a term as a product of its number part and variable part to identify the coefficient.
