What is Exponentiation?

Exponentiation is a mathematical operation that involves raising a base number to a certain power (exponent). It's written as b^n, where b is the base and n is the exponent. The result is b multiplied by itself n times.

Exponent Rules:

  • Product Rule: a^m × a^n = a^(m+n)
  • Quotient Rule: a^m ÷ a^n = a^(m-n)
  • Power Rule: (a^m)^n = a^(m×n)
  • Zero Exponent: a^0 = 1 (where a ≠ 0)
  • Negative Exponent: a^(-n) = 1/a^n
  • Fractional Exponent: a^(m/n) = n√(a^m)

Common Examples:

  • 2^3 = 2 × 2 × 2 = 8
  • 5^2 = 5 × 5 = 25
  • 10^4 = 10,000
  • 3^(-2) = 1/3^2 = 1/9
  • 16^(1/2) = √16 = 4

Applications:

  • Compound interest calculations
  • Population growth modeling
  • Scientific notation
  • Computer science and algorithms
  • Physics and engineering calculations
  • Cryptography and security
