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....
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...
