log函数是指数函数y = bx 的反函数,用于求数字以某个数为底的对数。log函数的定义:设b>0,b≠1,对于任意实数x > 0,如果存在唯一的实数y,使得 b^y = x,则称y为以b为底x的对数,记为:y = log_b(x)这里b称为对数的底数。对数运算的底数通常取10和e。
List of logarithmic identities - Wikipedia
The identities of logarithms can be used to approximate large numbers. Note that log b (a) + log b (c) = log b (ac), where a, b, and c are arbitrary constants. Suppose that one wants to approximate the 44th Mersenne prime, 2 32,582,657 −1. To get the base-10 logarithm, we would multiply 32,582,657 by log 10 (2), getting 9,808,357.09543 ...

The base b logarithm of a number is the exponent that we need to raise the base in order to get the number. The logarithm of the multiplication of x and y is the sum of logarithm of x and logarithm of y. The logarithm of the division of x and y is the difference of …
对数函数 - 百度百科
一般地,函数y=log aX (a>0,且a≠1)叫做对数函数,也就是说以幂(真数)为自变量,指数为因变量,底数为常量的函数,叫对数函数。

log 10 10,000 = 4. "The logarithm of 10,000 with base 10 is 4." 4 is the exponent to which 10 must be raised to produce 10,000. "10 4 = 10,000" is called the exponential form. "log 10 10,000 = 4" is called the logarithmic form. Here is the definition:
Logarithmic Equation Calculator - Symbolab
To solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. Set the arguments equal to each other, solve the equation and check your answer. A logarithmic equation is an equation that involves the logarithm of an expression containing a varaible.
