How exponents work
An exponent tells you how many times to multiply the base by itself: 2^3 = 2 × 2 × 2 = 8. A negative exponent means take the reciprocal: 2^(−2) = 1/2^2 = 1/4. A fractional exponent represents a root: 8^(1/3) = ∛8 = 2. Zero exponent always gives 1 for any non-zero base. These rules are fundamental in algebra, science, and engineering.
