How does this calculator work?
b^n raises any base to any exponent. Special cases: b^0 = 1, b^(−n) = 1/b^n, b^(½) = √b. The calculator handles integers, decimals and negative exponents, shows step-by-step working, and plots the power function b^x to illustrate exponential growth or decay.
Formula
How this is calculated
Exponentiation (written b^n or bⁿ) is repeated multiplication for positive integers: 2^4 = 2 × 2 × 2 × 2 = 16. The rule extends naturally to other cases: b^0 = 1 for any non-zero base; b^(−n) = 1 / b^n (reciprocal); b^(1/n) = the n-th root of b; and b^(p/q) = the q-th root of b^p.
This calculator uses IEEE-754 double-precision floating-point arithmetic (Math.pow), accurate to about 15–16 significant digits. Very large exponents overflow to ±Infinity; results are left undefined in that case. For negative bases with non-integer exponents, the result is complex (imaginary) and is not computed here — use a complex-number calculator for those cases.
The XY curve shows b^x as x sweeps from 0 to n, illustrating exponential growth (b > 1) or exponential decay (0 < b < 1) visually.
Frequently asked questions
b^(−n) = 1 / b^n. For example, 2^(−3) = 1 / 2^3 = 1 / 8 = 0.125. The base must be non-zero.
b^(1/n) is the n-th root of b. So 8^(1/3) = ∛8 = 2, and 16^(0.5) = √16 = 4. In general b^(p/q) = (b^p)^(1/q) — raise to the numerator, then take the denominator-th root.
The pattern b^3 → b^2 → b^1 continues by dividing by b each step, so b^0 = b^1 / b = 1. This holds for any non-zero base. The value of 0^0 is conventionally 1 in combinatorics and analysis, but mathematically indeterminate.
