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 ?
In this article, we are going to learn the definition of logarithms, two types of logarithms such as common logarithm and natural logarithm, and different properties of logarithms with many solved examples.
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.
Let us learn more about logarithms along with their properties with examples. What is Logarithm? Logarithm is nothing but another way of expressing exponents and can be used to solve problems that cannot be solved using the concept of exponents only. Understanding logs is not so difficult.
The logarithm of a number n refers to the number of times another number called the base, or b must be repeatedly multiplied to produce n. In other words, what the base b must be raised to get the number n is called n’s logarithm.
15 Οκτ 2014 · The logarithm base b of a number n is the number x that when b is raised to x th power, the resulting value is n. logbn = x ⇔ bx = n. Example: log28 = x. ⇒ 2x = 8. ⇒ 2x = 23. ⇒ x = 3. log51 = x. ⇒ 5x = 1. ⇒ 5x = 50. ⇒ x = 0. Answer link.
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 .
