UNIT 1 – RATIONAL NUMBERS, EXPONENTS AND SQUARE ROOTS Exponents: Expanded Form (Algebra 1. 1) 1. Which expression below is the expanded form of 54? a) b) c) d) 5 5 4 4 4 5 5 52 • In order to find the expanded form of the exponential expression 54, look at the exponent. The exponent indicates the number of times the base appears in the expanded form.

UNIT 1 – RATIONAL NUMBERS, EXPONENTS AND SQUARE ROOTS Exponents: Expanded Form (Algebra 1. 1) 1. Which expression below is the expanded form of 54? a) b) c) d) 5 5 4 4 4 5 5 52 • The exponent in the expression 54 is 4. So the expanded form of the exponential expression will be a multiplication of 4 fives. 5 5 The correct answer is (C).
