In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number. For example, the logarithm of 1000 to base 10 is 3, …

Learn the eight (8) log rules or laws to help you evaluate, expand, condense, and solve logarithmic equations. Try out the log rules practice problems for an even better understanding.

对数公式是数学中的一种常见公式，如果a^x=N (a>0,且a≠1)，则x叫做以a为底N的对数,记做x=log (a) (N)，其中a要写于log右下。 其中a叫做对数的底，N叫做真数 。 通常我们将以10为底的对 …

In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 …

log b (x) = y. For example when: 2 4 = 16. Then. log 2 (16) = 4. Logarithm as inverse function of exponential function. The logarithmic function, y = log b (x) is the inverse function of the …

2024年12月30日 · In mathematics, a logarithm is the inverse operation of exponentiation. It is defined as the power to which the base number must be raised to get the given number. …

2025年2月11日 · logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which …

Logb x = n or bn = x. Where b is the base of the logarithmic function. This can be read as “Logarithm of x to the base b is equal to n”. In this article, we are going to learn the definition of …

Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions" Doing one, then the other, gets us back to …

What are the Laws of Logarithms? The laws of logarithms are algebraic rules that allow for the simplification and rearrangement of logarithmic expressions. The 3 main logarithm laws are: …
