Exponent

Exponent

1. (Science: mathematics) 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.

thus a^2 denotes the second power, and a^n 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.

2. One who, or that which, stands as an index or representative; as, the leader of a party is the exponent of its principles. Exponent of a ratio, the quotient arising when the antecedent is divided by the consequent; thus, 6 is the exponent of the ratio of 30 to 5.

Origin: L. Exponens, -entis, p. Pr. Of exponere to put out, set forth, expose. See Expound.

... There're 23 letters using a set of both upper and lower case letters (26 + 26 = 52) plus 1 for the space (53) so the probability is 1 in 53 to an exponent of 23 using the multiplication rule. Example: Chances of rolling 1 and 1 on a 6-sided dice are 1 in 6 with an exp of 2 or 1 in 36. I wrote ...

Re: Beer Lambert Law

So what happened to your exponent on the power of ten? I didn't check the extinction coefficient (now preferably called the molar absorptivity) of NADH. I'll take your word for it that it is 6.22E3 A/ M cm. What you haven't told anyone ...

Mathematical Biology, metabolism, origins of life, evolution

... Kleiber's Law that includes the term for metabolic efficiency (ME). The equation deals with metabolic rate and biomass. The term ME occurs in the exponent of biomass, and is clearly a statement of efficiency of redox coupling. This means electrochemistry. Metabolic rate is then expressed in watts, ...

Geometric Progressions

Reducing the factor by which the geometric progression increases (lowering the value of the exponent) reduces the difference between numbers of people and amount of food production. It can be achieved by lowering family size or delaying childbearing.
