A number that indicates how many times to multiply the base by itself.

• A. Radius
• B. Exponent
• C. Fraction
• D. Average

Answer: (B)

Exponent notation shows how many times to multiply the base by itself. The exponent is that number, guiding how many factors of the base appear in the product. For example, in 3^4 you multiply 3 by itself four times: 3 × 3 × 3 × 3. The base is the number being multiplied, while the exponent (often called the power) tells you the count. Other terms like radius, fraction, or average refer to different concepts (distance in a circle, part of a whole, and a measure of center, respectively) and don’t describe repeated multiplication, so the exponent is the correct label.
