  2. Location of an Index • An index is a little number high and to the right of a regular or base number. Index 3 4 Base

  3. Definition of an Index • An index tells how many times the base number is multiplied by itself. Index 3 4 Base

  4. What an Index Represents • An index tells how many times the base number is multiplied by itself. 4 = 3 x 3 x 3 x 3 3

  5. How to read an Index • This index is read three to the power of four. index 3 4 Base

  6. How to read an Index • This index is read three to the power of two or three squared. index 3 2 Base

  7. How to read an Index • This index is read three to the power of three or three cubed. index 3 3 Base

  8. Read These Indices 3 2 6 7 2 3 5 4

  9. What is the index? 3 2 x 2 x 2 = 2

  10. What is the index? 2 3 x 3 = 3

  11. What is the index? 4 5 x 5 x 5 x 5 = 5

  12. What is the Base and the Index? 4 8 x 8 x 8 x 8 = 8

  13. What is the Base and the Index? 5 7 x 7 x 7 x 7 x 7 = 7

  14. What is the Base and the Index? 9 x 9 = 9 2

  20. Indices Are Used in Area Problems to Show the Units Used 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

  21. Indices Are Used in Volume Problems to Show the Units Used 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. 20 10 10 3

  22. Here Are Some AreasChange The Units To Indices 2 40 cm squared = 40 cm. 56 sq. m = 56 m. 38 m. squared = 38 m. 56 sq. mm. = 56 mm. 2 2 2

  23. Here Are Some VolumesChange The Units To Indices 3 30 km cubed = 30 km. 26 cu. mm = 26 mm. 44 m. cubed = 44 m. 56 cu. cm. = 56 cm. 3 3 3
