Apply index laws to algebraic expressions involving negative-integer indices
- Apply index notation, patterns and index laws to establish a^(- 1) = 1/a, a^(- 2) = 1/a², a^(- 3) = 1/a³ and a^(- n) = 1/aⁿ 3 resources · 1 interactive/game
- Represent expressions involving negative- integer indices as expressions involving positive-integer indices and vice versa 2 resources
- Apply the index laws to simplify algebraic products and quotients involving negative-integer indices 1 resource
- Describe and use x^(- 1) as the reciprocal of x and generalise this relationship to expressions of the form (a/b)^(- 1)
- Use knowledge of the reciprocal to simplify expressions of the form (a/b)^(- n)
