  1. Indices Learning objective: To understand the basic rules of indices - all To investigate powers of 0 and 1 - most To investigate negative powers - some You will require a scientific calculator and a pen.

  2. Investigation

  3. Rules of indices Multiplication xa * x b =x(a + b) Division xa÷ xb = x(a-b) Powers (xa)b = x(ab)

  4. Exercise • 3³ x 34 = 2) 7103 ÷ 7101 = 3) (8³)² = 4) (2³ ÷ 2²)5 =

  5. Further investigation What is x0? What is x1? Where x can be any number. What is the effect of negative powers?

  6. Further investigation
