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. So the logarithm is 3. How to Write it. We write it like this: log2(8) = 3. So these two things are the same:
1 ημέρα πριν · Log Rules: The Product Rule. The first of the natural log rules that we will cover in this guide is the product rule: logₐ (MN) = logₐM + logₐN. Figure 03: The product rule of logarithms. The product rule states that the logarithm a product equals the sum of the logarithms of the factors that make up the product.
A common log is a logarithm with base 10, i.e., log 10 = log. A natural log is a logarithm with base e, i.e., log e = ln. Logarithms are used to do the most difficult calculations of multiplication and division. ☛ Related Topics: Common Log Calculator; Natural Log Calculator
A logarithm is the inverse of the exponential function. Specifically, a logarithm is the power to which a number (the base) must be raised to produce a given number. For example, \log_2 64 = 6, log2 64 = 6, because 2^6 = 64. 26 = 64. In general, we have the following definition: z z is the base- x x logarithm of y y if and only if x^z = y xz = y.
The logarithmic function, y = log b (x) is the inverse function of the exponential function, x = by. So if we calculate the exponential function of the logarithm of x (x>0), f (f -1 (x)) = blogb(x) = x. Or if we calculate the logarithm of the exponential function of x, f -1 (f (x)) = log b (bx) = x.

Logarithms are the inverse operation of exponentiation. We can use logarithms to find the exponent to which a given base must be raised in order to produce a particular result. For example, log 2 8 = 3 , because 2 3 = 8 .
