Quotient of Powers Rule

Algebra-1

1. Fundamental Concepts

  • Definition: The Quotient of Powers Rule states that when dividing two powers with the same base, you subtract the exponents.
  • Rule: For any non-zero number and integers and , .
  • Zero Exponent Rule: Any non-zero number raised to the power of zero is 1, i.e., .

2. Key Concepts
