From The Collaborative International Dictionary of English v.0.48 :

  Exponent \Ex*po"nent\, n. [L. exponens, -entis, p. pr. of
     exponere to put out, set forth, expose. See Expound.]
     1. (Alg.) A number, letter, or any quantity written on the
        right hand of and above another quantity, and denoting how
        many times the latter is repeated as a factor to produce
        the power indicated;
  
     Note: thus a^{2 denotes the second power, and a^{x} the xth
           power, of a (2 and x being the exponents). A fractional
           exponent, or index, is used to denote the root of a
           quantity. Thus, a^{1/3 denotes the third or cube root
           of a.
