n就是以e为底的log，lna可写成loge a。lg就是以10为底的log。log(c)(a*b)=log(c)a+log(c)b －－相当于同底数幂相乘,底数不变“指数相加”。log(c)(a/b)=log(c)a/log(c)b －－相当于同底数幂相除,底数不变“指数相减” 。log(c)(a^n)=n*log(c)a －－相当于幂的乘方,底...
e、ln和log是指数与对数函数中常用的三个数学常数和函数。1. e是一个数学常数，称为自然对数的底或欧拉常数，其近似值为2.71828。2. ln(x)是以e为底的对数函数，表示x的自然对数。ln(x)的定义是e raised to the power of y equals x的逆运算，即e^ln(x) = x。3. log(x)是以10为底...
Logarithm power ruleThe logarithm of x raised to the power of y is y times the logarithm of x.logb(x y) = y ∙ logb(x)For example:log10(28) = 8∙ log10(2)Logarithm base switch ruleThe base b logarithm of c is 1 divided by the base c logarithm of b....

a logarithm (to base b) of a number x is the exponent y of the power by such that x = by. The value used for the base b must be neither 0 nor 1 (nor a root of 1 in the case of the extension to plex numbers)and is typically 10 e or 2. The base-b logarithm ...
