Vocabulary Factor – p. 16 – when whole numbers other than zero are multiplied together, each number is a factor of the product . Power – p. 16 – an expression, such as 2 3 , that represents a product with a repeated factor. Base – p. 16 – the base of a power is the repeated factor (the number written large). Exponent – p. 16 – the exponent of a power is the number of times the factor is repeated (the number written up and small).
Powers, Bases, and Exponents The base of a power is the repeated factor and the exponent is the number of times a factor is repeated. 6 3 base exponent = 6 x 6 x 6 power There are 3 factors
