Page 1: Rules of Indices and Core Concepts

This page introduces fundamental rules for working with indices and covers multiplication, division, and negative powers. The content explains how to handle various types of indices calculations with detailed examples.

Definition: When multiplying indices, add the powers (e.g., 2a² × a³ = 2a⁵)

Highlight: For negative indices, the number becomes its reciprocal (e.g., 3⁻² = 1/3²)

Example: When working with fractional powers: 27²/³ = (√27)² = 9

Vocabulary: Numerator - the top number in a fraction; Denominator - the bottom number in a fraction

The page elaborates on working with fractions and introduces the concept that negative powers mean flipping fractions. It also covers the essential rule for fractional powers where the denominator represents the root and the numerator represents the power.

Page 2: Advanced Applications and Complex Calculations

This page delves deeper into advanced applications of indices, focusing on working backwards and solving more complex problems involving negative and fractional powers.

Definition: When working with fractional powers, am/n = (√a)m where n represents the root and m the power

Example: 25⁻³/² = 1/(25³/²) = 1/125

Highlight: For decimal powers, convert to fractions before solving (e.g., 0.16 = 16/100)

The page provides comprehensive guidance on solving complex indices problems, particularly focusing on negative fractional powers and working backwards. It emphasizes the importance of breaking down complex calculations into manageable steps and applying the correct rules systematically.
