exposent

Exposent is not a standard term in English mathematics. In most contexts, it is either a misspelling or a confusion with exponent, or it is the French noun exposant meaning the exponent in a power expression, or the French verb exposer in its present tense form exposent meaning they expose. Consequently, there is no independent mathematical definition for exposent in widely used sources.

When people mean exponent, they refer to the exponent of a^b, where a is the base and b the exponent. The exponent indicates how many times to multiply the base by itself. Examples: 3^4 = 81; a^0 = 1 for nonzero a; a^-n = 1/a^n. Exponentiation obeys laws such as a^m * a^n = a^(m+n) and (ab)^n = a^n b^n. Exponents can be integers, fractions, or irrational numbers. For real-number exponents, a^b is defined when a > 0; complex exponents extend the concept further.

In French mathematics, the exponent is called l'exposant. In that context, exposant serves the same role as the English "exponent."

If the term appears in software or branding, its meaning would depend on the specific usage in that context, not on a universal mathematical definition.
