Laws of Indices and Square Numbers

  Laws of Indices and Square Numbers Laws of Indices Indices are used to show that a number is being multiplied by itself. For example: 2³ means 2 × 2 × 2 3² means 3 × 3 The laws of indices are used to simplify expressions that involve indices. Positive Indices A positive index shows that a number is being multiplied by itself. For example: 2³ = 2 × 2 × 2 = 8 3² = 3 × 3 = 9 Zero Indices Any number with a zero index is equal to 1. For example: 2⁰ = 1 3⁰ = 1 Laws of Indices There are several laws of indices that can be used to simplify expressions: Multiplication Law : aᵐ × aⁿ = aᵐ⁺ⁿ Division Law : aᵐ ÷ aⁿ = aᵐ⁻ⁿ Power Law : (aᵐ)ⁿ = aᵐ×ⁿ Applying the Laws of Indices Using the laws of indices, we can simplify expressions such as: 2³ × 2² = 2³⁺² = 2⁵ 3² ÷ 3¹ = 3²⁻¹ = 3¹ (2²)³ = 2²×³ = 2⁶ Here is the revised text: Laws of Indices Multiplication Law When multiplying powers with the same base, add the exponents. aᵐ × aⁿ = aᵐ⁺ⁿ Examples 2³ × 2⁵ = 2³⁺⁵ = 2⁸ 3² × 3⁴ = 3²⁺⁴ = 3⁶ Division Law ...
