exponential

mathematics The exponent is the part of an expression indicating the power to which a term is raised, i.e. the x in ax, whether x is an integer, some other number, or some elaborate expression itself. An exponential function involves one or more such terms, the members of a geometric series being simple examples.

The term exponential series is also used within mathematics to describe the series that converges on the special number e.

 
Columbia Encyclopedia: exponent

exponent, in mathematics, a number, letter, or algebraic expression written above and to the right of another number, letter, or expression called the base. In the expressions x2 and xn, the number 2 and the letter n are the exponents respectively of the base x. The exponent indicates the power to which the base is to be raised. When exponents were first introduced, only positive whole numbers were used, and the exponent indicated how many times the base was to be taken as a factor; e.g., 25=32, or 2·2·2·2·2=32. In advanced algebra, fractions, zero, and negative numbers are also used as exponents. Particular meanings have been assigned to these types of exponents so that they obey the same algebraic rules as does the simpler type of exponent. A fractional exponent such as 1/4 or 1/n indicates the fourth or nth root, respectively, of the base. Any nonzero quantity raised to the zero power equals one; e.g., x0=50=(a2+b2)0=1. A negative exponent indicates the reciprocal of the quantity; e.g., x−2 means 1/x2. When quantities of the same base are multiplied together, their exponents are added; e.g., x2·x3=x5. Note that the base must be the same. When a quantity already containing an exponent is raised to a power, the exponents are multiplied; e.g., (x2)3=x6.


Science Dictionary: exponent

A number placed above and to the right of another number to show that it has been raised to a power. For example, 32 indicates that 3 has been raised to a power of 2, or multiplied by itself; 32 is equal to 9.

An exponent is a phonological manifestation of a morphosyntactic property. In non-technical language, it is the expression of one or more grammatical properties by sound. There are several kinds of exponents:

  • identity
  • affixation
  • reduplication
  • internal modification

Contents

Identity

The identity exponent is both simple and common: it has no phonological manifestation at all.

English example:
DEER + PLURAL → deer

Affixation

Affixation is the addition of a prefix, suffix or infix to a word.

English example:
WANT + PAST → wanted

Reduplication

Reduplication is the repetition of part of a word.

Sanskrit Example:
DA ('give') + PRESENT + ACTIVE + INDICATIVE + FIRST PERSON + SINGULARdadaami (the da at the beginning is from reduplication, a characteristic of class 3 verbs in Sanskrit)

Internal modification

There are several types of internal modification. An internal modification may be segmental, meaning it changes a sound in the root.

English example:
STINK + PAST = stank (i becomes a)

An internal modification might be a [suprasegmental] modification. An example would be a change in pitch.

A slightly controversial exponent is subtraction, in which a sound or group of sounds is removed. Some people don't think this happens.
