What is an exponent?
An exponent tells you how many times to multiply a number, the base, by itself. In 2⁵, the base is 2 and the exponent is 5, so the value is 2 × 2 × 2 × 2 × 2 = 32. Exponents are a compact way to write repeated multiplication and appear throughout science, finance and computing.
How exponents work
A positive whole exponent means repeated multiplication: 2¹⁰ = 1024. A zero exponent always gives 1 (any non-zero number to the power 0 is 1). A negative exponent means the reciprocal: 2⁻³ = 1 ÷ 2³ = 0.125. A fractional exponent means a root: raising to the power ½ is a square root and to ⅓ a cube root, so 9^½ = 3.
Example
2¹⁰ means 2 multiplied by itself ten times, which equals 1024. As another example, 5³ = 5 × 5 × 5 = 125, and 2⁻³ = 1 ÷ (2 × 2 × 2) = 0.125.

How to use
Enter the base and the exponent, then read the result. The calculator handles whole-number, negative, and fractional powers.
A negative base with a fractional exponent has no real value and is flagged as undefined. Very large or very small results are shown in scientific notation.
