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)

What are the changes of conditions for? With their assistance, you can understand conditions. How? Certain changes, which will be examined in the following section, enable us to move from a condition to an identical condition or condition impact. Handy utilization of such changes makes it conceivable to construct a chain of proportionate conditions and conditions results with a genuinely basic arrangement as far as a limited condition, which enables you to discover every one of the underlying foundations of the first condition by the foundations of the last condition.
