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
