Logarithm Calculator

Calculate logarithm of a number to any base:


* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12


b y = x

Then the base b logarithm of a number x:

logb x = y

Anti-logarithm calculator

In order to calculate log-1(y) on the calculator, enter the base b (10 is the default value, enter e for e constant), enter the logarithm value y and press the = or calculate button:



y = logb x

The anti logarithm (or inverse logarithm) is calculated by raising the base b to the logarithm y:

x = logb-1(y) = b y

Logarithm rules

Logarithm product rule

logb(x × y) = logb(x) + logb(y)

Logarithm quotient rule

logb(x / y) = logb(x) - logb(y)

Logarithm power rule

logb(x y) = y × logb(x)

Logarithm base switch rule

logb(c) = 1 / logc(b)

Logarithm base change rule

logb(x) = logc(x) / logc(b)

Decrease of divisions to another denominator - the standard and examples.In this article we will discuss throwing parts to another denominator. To begin with, we will comprehend what is known as the decrease of the portion to a shared factor. From that point onward, we give the meaning of an extra factor and figure out how to locate an extra factor that leads the first portion to the denominator showed. At long last, we will voice the standard of throwing a portion to another
