ETYM Latin exponens, -entis, p. pr. of exponere to put out, set forth, expose. Related to Expound.
In mathematics, a number that shows how many times a number is used as a factor in a calculation; in other words, an exponent shows that number’s power. Positive exponents, as in 23, indicate multiplication (2 times 2 times 2). Negative exponents, as in 2-3, indicate division (1 divided by 23). Fractional exponents, as in 81/3, indicate the root of a number (the cube root of 8).
Or index; In mathematics, a number that indicates the number of times a term is multiplied by itself; for example x2 = x x x, 43 = 4 x 4 x 4.
Exponents obey certain rules. Terms that contain them are multiplied together by adding the exponents; for example, x2 x x5 = x7. Division of such terms is done by subtracting the exponents; for example, y5 ÷ y3 = y2. Any number with the exponent 0 is equal to 1; for example, x0 = 1 and 990 = 1.
