* Logarithm, the exponent or power to which a base must be raised to yield a given number*. Expressed mathematically, x is the logarithm of n to the base b if b x = n, in which case one writes x = log b n.For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log 2 8. In the same fashion, since 10 2 = 100, then 2 = log 10 100. Logarithms of the latter sort (that is, logarithms. En speciell bas är e (Eulers tal). Beteckningen för log e a, den naturliga logaritmen av a, är ln a.. Detta ger sambanden = ⇔ = . En viktig anledning till att denna logaritm används är att den är den inversa funktionen till exponentialfunktionen e x.. En intressant egenskap hos den naturliga logaritmfunktionen är att dess derivata är 1/x, vilket gör att den fyller ut en lucka. Common Logarithms: Base 10.
