Laws of Indices

What is the resource?

This PDF offers a reference sheet about index notation (powers). It explains rules for simplifying expressions like x² multiplied by x³, etc. Designed for secondary learners.


Why are index laws important?

They open up more advanced maths and have surprising real-world applications:

  • Scientific notation: Tiny or huge numbers get manageable for physicists, astronomers etc.
  • Compound growth: Used in finance to analyse how investments change over many years.
  • Computer coding: Binary (bases and powers) is the heart of how programming languages function.
  • Spread of trends: Exponential models help predict how fast ideas or infections may spread in a group.


Why is this resource helpful?

This 'cheat sheet' format aids review and helps overcome memory-based 'stumbling blocks':

  • Clear rules summarised: Includes examples showing each law in action, in short terms.
  • Common errors noted: Highlights where students most often slip up, encouraging self-checking.
  • Builds fluency: Reduces panic at seeing powers; lets kids focus on wider problems, not just the basics.
  • Printable PDF: Ideal as an in-class handout, on displays, or included with exam revision tasks.

This resource makes indices less intimidating. Students develop the comfort level needed to apply these rules seamlessly throughout maths & related fields.
