Calculate bn
Exponents Explained
bn means multiply b by itself n times. Example: 2³ = 2 × 2 × 2 = 8.
Negative exponents: b-n = 1 / bn. Example: 2-3 = 1/8 = 0.125.
Fractional exponents: b1/n is the nth root of b. Example: 81/3 = ∛8 = 2.
Zero exponent: Any non-zero number raised to 0 equals 1. b0 = 1.
Scientific notation expresses numbers as a coefficient (1 ≤ c < 10) times a power of 10.
Frequently Asked Questions
An exponent (or power) indicates how many times to multiply a base number by itself. In b^n, b is the base and n is the exponent. Example: 3^4 = 3 × 3 × 3 × 3 = 81.
A negative exponent means take the reciprocal. b^-n = 1 / b^n. For example, 2^-3 = 1/8 = 0.125.
A fractional exponent represents a root. b^(1/n) is the nth root of b. For example, 27^(1/3) = ∛27 = 3.
Scientific notation writes very large or very small numbers as a coefficient (between 1 and 10) multiplied by a power of 10. Example: 450,000 = 4.5 × 10^5.
