  • An exponent tells how many times the base is used as a repeated factor.
  • The plural of index is indices.

2. Exponential Form of Numbers

  • 625 = 5 × 5 × 5 × 5 = 5^4.
  • 32 = 2 × 2 × 2 × 2 × 2 = 2^5.
  • 729 = 3 × 3 × 3 × 3 × 3 × 3 = 3^6.

3. Laws of Exponents

  • First Law: same base multiplication means add the exponents.
  • Second Law: same base division means subtract the exponents.
  • Third Law: power raised to another power means multiply the exponents.

4. Zero Index, Negative Index, and Roots

  • Any non-zero base raised to power zero equals 1.
  • a^0 = 1 if a ≠ 0.
  • a^-m = 1/a^m and 1/a^-m = a^m when a ≠ 0.
