内容如下：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...
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...

log10(3/7) = log10(3)-log10(7) Logarithm power rule The logarithm of x raised to the power of y is y times the logarithm of x. logb(xy) =y ∙logb(x) For example: log10(28) = 8∙log10(2) Logarithm base switch rule ...

In mathematics 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...
定义:若 an=b(a>0,a≠1)则 n=logab。 2,换底公式 logMN=logaM/logaN 换底公式导出 logMN=-logNM 3,推导公式 log(1/a)(1/b)=log(a^-1)(b^-1)=-1logab/-1=loga(b) loga(b)*logb(a)=1 loge(x)=ln(x) lg(x)=log10(x)
