COURSE DESCRIPTION
Exponents (or indices) can feel intimidating at first — all those little numbers floating above the base. But once you understand the rules, they’re actually one of the most powerful shortcuts in mathematics. This course is designed for 9th grade students who want to make sense of index laws, build confidence, and apply them not only in exams but also in real-world situations like science, finance, and technology.
Through clear explanations, step-by-step examples, and plenty of practice, you’ll discover that indices aren’t just abstract symbols — they’re tools that make complex calculations surprisingly simple.
What you’ll learn
1. Introduction to Indices
-
What are indices (exponents)?
-
Understanding base and index (e.g., 2³ = 2 × 2 × 2 = 8)
-
Simple practice: writing repeated multiplication in index form
2. Index Laws
-
Law 1: Multiplying Powers → aᵐ × aⁿ = aᵐ⁺ⁿ
-
Law 2: Dividing Powers → aᵐ ÷ aⁿ = aᵐ⁻ⁿ
-
Law 3: Power of a Power → (aᵐ)ⁿ = aᵐˣⁿ
-
Law 4: Power of a Product → (ab)ⁿ = aⁿbⁿ
-
Zero Index Rule → a⁰ = 1
-
Negative Index Rule → a⁻ⁿ = 1/aⁿ
3. Common Misconceptions
-
Mixing up multiplication and power laws
-
Thinking a⁰ = 0 instead of 1
-
Confusion with negative exponents
4. Practice Worksheets
-
Part A: Basic Index Notation
-
Part B: Laws of Indices
-
Part C: Zero & Negative Indices
-
Part D: Mixed Practice & Challenge Problems
5. Advanced Indices
-
Simplifying complex expressions
-
Positive vs negative powers
-
Exponents in algebraic terms
6. Real-World Applications
-
Scientific notation in physics & chemistry
-
Compound interest in finance
-
Population growth & decay in biology
-
Computer processing power (Moore’s Law)
Assessments & Activities
Learning sticks best when you can apply it. That’s why this course includes:
- Quick quizzes for instant feedback
- Short-answer problems to test your reasoning
- Extended questions that connect maths to real life
- Reflection activities so you can track your progress
An answer key is provided for independent learning, but you’ll also be guided through step-by-step solutions.
