Achievement objective M7-6

In a range of meaningful contexts, students will be engaged in thinking mathematically and statistically. They will solve problems and model situations that require them to:

  • manipulate rational, exponential, and logarithmic algebraic expressions.


  • Makes links between the concepts, properties, and manipulation of exponents and logarithms, and the inverse relationship between them.
  • Solves problems that involve manipulating rational, exponential, and logarithmic algebraic expressions. Methods that could be used in solving problems include:
    • simplifying algebraic expressions including rational expressions
    • expanding and factorising
    • manipulating expressions with exponents including fractional and negative exponents
    • manipulating logarithms in order to solve exponential equations
    • simplifying expressions including logarithms involving the power rule and also products and quotients.
  • Makes links with solving equations M7-7 and graphing functions M7-2.
  • See key mathematical ideas on NZmaths.


M7-6 links from NA6-2, NA6-6 and to M8-6, M8-9.
