1. Exponents and Exponential Form

2. 24 Exponents Exponents tell us the power of the base unit, or number.
Base Unit is the number you will be multiplying
Exponent represents the amount of times you multiply

5. Exponents Are Often Used in Area Problems to Show the Feet Are Squared
Length x width = area
A pool is a rectangle
Length = 30 ft.
Width = 15 ft.
Area = 30 x 15 = 450 ft.
15ft.
30ft 2

6. Length x width x height = volume A box is a rectangle Length = 10 cm.
Exponents Are Often Used in Volume Problems to Show the Centimeters Are Cubed
Length x width x height = volume
A box is a rectangle
Length = 10 cm.
Width = 10 cm.
Height = 20 cm.
Volume =
20 x 10 x 10 = 2,000 cm. 10 10 10 3
