Frequently asked questions
What is 2 to the power of 10?
1024 — a chain of ten factors of 2. Enter base 2 and exponent 10 above and the calculator multiplies them out step by step.
Do fractional and negative exponents work?
Yes. A fractional exponent is a root: 16^(1/2) = 4 and 8^(1/3) = 2. A negative exponent is a reciprocal: 2^(−3) = 1/2³ = 0.125.
What about negative bases?
Whole-number exponents are fine: (−2)³ = −8 and (−2)² = 4. A negative base with a fractional exponent has no real value, so the calculator returns no result for that case.
What does an exponent of zero mean?
Any non-zero number raised to the power 0 equals 1: 8⁰ = 1. The rule follows from dividing equal powers: 8⁵ ÷ 8⁵ = 1, and subtracting exponents gives 8⁰. Enter 0 as the exponent above and the calculator returns 1. The same holds for 7⁰, 100⁰, and 0.5⁰.
