Frequently Asked Questions

What does a negative exponent mean?
A negative exponent means take the reciprocal: x⁻ⁿ = 1 / xⁿ. For example, 2⁻³ = 1 / 2³ = 1/8 = 0.125.
What is a fractional exponent?
A fractional exponent represents a root: x^(1/n) is the nth root of x. For example, 8^(1/3) = ∛8 = 2. More generally, x^(m/n) = (nth root of x)^m.
Can I calculate very large exponents?
Yes. Results for very large exponents are displayed in scientific notation. For extremely large integers (like 2^1000), the full integer may be shown if it fits within JavaScript's BigInt precision.
