Introduction to Logarithms - Math is Fun
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 × 2 = 8, so we had to multiply 3 of the 2 s to get 8. We write it …
Basic idea and rules for logarithms - Math Insight
The basic idea. A logarithm is the opposite of a power. In other words, if we take a logarithm of a number, we undo an exponentiation. Let's start with simple example. If we take the base $b=2$ and raise it to the power of $k=3$, we have the expression $2^3$. The result is some number, we'll call it $c$, defined by $2^3=c$.

Introduction to Logarithm - GeeksforGeeks
4 天之前 · Logarithm is a mathematical function that represents the exponent to which a fixed number, known as the base, must be raised to produce a given number. In other words, it is the inverse operation of exponentiation. Mathematical Expression for Log. If a n = b then log or logarithm is defined as the log of b at base a is equal to n. It should be noted that in both …
