| 单词 | logarithm |
| 释义 | logarithm The power to which any base number over 1 needs to be raised to give any positive number. If x is the log to base y of z then z = yx. Logarithms have the property that the logarithm of the product of any two numbers is the sum of the logs of the two numbers. Logarithms can be taken to any base over 1: the two forms most commonly used are logarithms to base 10, written log(x), and natural logarithm to base e, written ln(x); these are provided by most calculating machines. ln(x) is the indefinite integral of 1/x.
