In the term 3a²b, which is the variable part?
Answer and explanation
Correct answer: a²b
An algebraic term can be separated into its numerical coefficient and its variable part. In 3a²b, the number 3 is the coefficient, while the variables and their powers form a²b. Thus option D is correct. Options B and C incorrectly retain the coefficient 3, and option A names only the numerical coefficient rather than the variable portion.
