Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.
Example: 2 3 = 8 => log 2 8 = 3 the base is 2. Animated explanation of logarithms. There are standard notation of logarithms if the base is 10 or e.
In mathematics, the logarithm to base b is the inverse function of exponentiation with base b. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.
29 Ιουλ 2024 · According to the product rule, the logarithm of a product is the sum of the logarithms of its elements. Formula: loga(XY) = logaX + logaY. Example: log2(3 × 5) = log2(3) + log2(5) The quotient rule asserts that the logarithm of a quotient equals the difference of the numerator and denominator logarithms. Formula: loga(X/Y) = logaX – logaY.
28 Μαΐ 2024 · Logarithm, often called ‘logs,’ is the power to which a number must be raised to get the result. It is thus the inverse of the exponent and is written as: b a = x ⇔ log b x = a. Here, are the 3 parts of a logarithm. Thus, the logarithm represents the exponent to which a base is raised to yield a given number. For example, we know 4 3 = 64.
Sometimes a logarithm is written without a base, like this: This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number.
This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.
