3. 1-6-3 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. Exponential Notation Exponential notation is a shorthand way of expressing repeated multiplication. In exponential notation, the base is the factor that is multiplied repeatedly. In exponential notation, the exponent or power is the number that indicates how many times the base is used as a factor. base → ← exponent
