Understanding Exponents
Exponents are a fundamental concept in mathematics, particularly relevant for the GMAT. They denote repeated multiplication of a number by itself. Grasping the rules and properties of exponents is crucial for success in quantitative sections.
Key Properties of Exponents
  • Product of Powers: \(a^m \times a^n = a^{m+n}\)
  • Quotient of Powers: \(a^m \div a^n = a^{m-n}\)
  • Power of a Power: \((a^m)^n = a^{m \cdot n}\)
  • Power of a Product: \((ab)^n = a^n \times b^n\)
  • Power of a Quotient: \(\left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}\)
  • Zero Exponent: \(a^0 = 1\) (where \(a \neq 0\))
  • Negative Exponent: \(a^{-n} = \frac{1}{a^n}\)


Practice Problems
Familiarize yourself with these properties through practice problems. Here are a couple of examples:
1. Simplify \(x^3 \times x^4\).
2. Calculate \(\frac{y^5}{y^2}\).
3. Evaluate \((2^3)^2\).
Preparation Tips
  • Review Basic Concepts: Ensure clarity on the definitions and rules.
  • Practice Regularly: Use GMAT Focus Edition Mock Test Series 2024 for practice.
  • Identify Weak Areas: Focus on solving problems that challenge your understanding.


Mastering exponents is essential for tackling the GMAT, and consistent practice will build your confidence.
