Negative bases with fractional exponents can produce imaginary results — the calculator shows real values only.
How it works
Result = base^exponent. Negative exponent: base^(−n) = 1/baseⁿ.
Example: 2¹⁰ = 1024; 2⁻¹ = 0.5.
Frequently Asked Questions
What is an exponent?
An exponent says how many times to multiply the base by itself. In 2¹⁰ the base is 2 and the exponent is 10, so the result is 2 × 2 × ... ten times = 1024.
What does a negative exponent mean?
A negative exponent means the reciprocal: 2⁻¹ = 1/2. The result is always between 0 and 1 for a positive base.
What is 2 to the power of 0?
Any non-zero number raised to the power 0 equals 1. This is a standard mathematical convention.
Where are exponents used in real life?
Compound interest, population growth and data sizes all rely on exponents — 2¹⁰ = 1,024 bytes in a kilobyte. Anything that doubles over time is exponential growth.
