# Logarithm Calculator

Calculate logarithm of a number to any base:

 log Result: Description:

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

When:

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:

 Result:

When

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)

Proportionate Equations and Corollary Equations - There are changes of conditions that enable one to go from the condition to be tackled to the alleged identical conditions and outcome conditions, by the arrangements of which it is conceivable to decide the arrangement of the first condition. In this article, we will break down in detail which conditions are called proportionate and which conditions are outcomes, give the fitting definitions, give illustrative models and disclose how to discover the foundations of the condition from the known underlying foundations of the comparable condition and condition result.
