What is an exponent?

• A. A shorthand method of indicating repeated addition
• B. A shorthand method of indicating repeated multiplication
• C. A type of prime number
• D. A method of calculating divisors

Answer: (B)

An exponent is indeed a shorthand method of indicating repeated multiplication. It is used to express how many times a number, known as the base, is multiplied by itself. For example, in the expression \(2^3\), the base is 2, and the exponent is 3, indicating that 2 should be multiplied by itself a total of three times (i.e., \(2 \times 2 \times 2 = 8\)). This notation simplifies the representation of large products, making it easier to work with and communicate. The concept of exponents originates from early mathematical practices and is fundamental to various areas of mathematics, including algebra, calculus, and beyond. The other options do not accurately describe the role of exponents: the repeated addition mentioned in the first option pertains more closely to basic arithmetic concepts like sums, while prime numbers and methods of calculating divisors focus on different aspects of number theory. Therefore, recognizing an exponent as a representation of repeated multiplication is essential for understanding its application in mathematics.
