AA variable
BA constant
CA coefficient
DAn exponent
Answer & Solution
Correct answer: A. A variable
1. The rule for algebra states that a letter representing a number whose value may change is called a variable.
2. A constant is a number whose value always stays the same, which is the opposite idea.
3. A coefficient is the number multiplying a variable, and an exponent is the small raised number, so neither fits the description.
