Logarithm definition math

WitrynaIn other words, The logarithm of a number ywith respect to a base bis the exponent to which we have to raise bto obtain y. We can write this definition as x = logby ---> bx= y and we say that xis the logarithm of ywith base bif and only if bto the power xequals y. WitrynaLogarithms or logs are a part of mathematics.They are related to exponential functions.A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation.Historically, they were useful in multiplying or dividing large numbers.

In mathematics, the logarithm is the inverse function to exponentiation. That means 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 = 10 , the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. The logarithm of x to base b is denoted as … Zobacz więcej Addition, multiplication, and exponentiation are three of the most fundamental arithmetic operations.
