Laws of exponents

aᵐ · aⁿ = aᵐ⁺ⁿ	Product of same-base powers: add exponents
aᵐ ÷ aⁿ = aᵐ⁻ⁿ	Quotient of same-base powers: subtract exponents
(aᵐ)ⁿ = aᵐⁿ	Power of a power: multiply exponents
(ab)ⁿ = aⁿbⁿ	Power of a product distributes
a⁰ = 1 (a≠0)	Any nonzero number to the 0th power is 1
a⁻ⁿ = 1/aⁿ	Negative exponent means reciprocal
a^(1/n) = ⁿ√a	Fractional exponent means root

💡 Fractional exponents are roots: x^0.5 = √x, x^(1/3) = ∛x. Compound interest is exponentiation in disguise: 1.05^12 is +5% compounded 12 times. To estimate 2^n by heart: 2^10 ≈ 10³, so 2^64 = 2^4 × (2^10)⁶ ≈ 16×10¹⁸.
