Which term is defined as the number of times a number occurs as a factor, as indicated by an exponent?

• A. Power
• B. Radical
• C. Vertex
• D. Width

Answer: (A)

The key idea is how exponents show repetition of a factor. When you see something like a^n, the base a is used as a factor n times. The term that names this idea—the count of how many times the base appears as a factor—is described by that word power. So the best answer is power. The other terms don’t fit because radical relates to roots, vertex is a point on a graph, and width is a dimension; none describe the repeated factor counted by the exponent.
