The word "exponent" originates from Latin exponere ("to put forth, explain"), combining ex- (out) and ponere (to put). The morpheme pon (from ponere) appears in many English words (e.g., "component," "postpone"). Over time, "exponent" evolved to denote someone who "puts forth" ideas (an advocate) and later acquired its mathematical sense (a number "put forth" as a power).
