Step 1: Setup the Problem…Expand the Problem Exponents Step 1: Setup the Problem…Expand the Problem 24 2∙2∙2∙2

Step 2: Solve the expanded form Exponents Step 2: Solve the expanded form 2∙2∙2∙2 4∙2∙2 8∙2 16

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

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
