WEBIntroduction to Logarithms. 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.
Logarithm - Wikipedia
WEBv. t. e. In mathematics, the logarithm is the inverse function to exponentiation. 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 …

WEBApr 15, 2024 · 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 case one writes x = log b n. For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log 2 8. In the same fashion, since 10 2 = 100, then 2 = log 10 100.

WEBLogarithms serve several important purposes in mathematics, science, engineering, and various fields. Some of their main purposes include: Solving Exponential Equations: Logarithms provide a way to solve equations involving exponents. When you have an equation of the form a^x = b, taking the logarithm of both sides allows you to solve for x.

WEBA 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.

WEBIn Mathematics, logarithms are the other way of writing the exponents. A logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 10 2 = 100 then log 10 100 = 2. Hence, we can conclude that, Log b x = n or b n = x

WEBA logarithm is the inverse function of exponentiation. A logarithm tells us the power, y, that a base, b, needs to be raised to in order to equal x. This is written as: log b (x) = y. Example. Write the equivalent of 10 3 = 1000 using logarithms. Two of the most commonly used bases are base 10 (common logarithm) and base e (natural logarithm).
