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)

Frequently, when comprehending conditions, the accompanying changes are utilized: Replacement of articulations that are in the left and right sides of the condition, indistinguishably equivalent articulations. Adding a similar number to the two sides of the condition or subtracting a similar number from the two sides of the condition. Adding to the two sides of the condition of a similar articulation or subtracting from the two sides of the condition of a similar articulation. The exchange of the term starting with one piece of the condition then onto the next with the sign changed to the inverse. Increase or separation the two sides of the condition by the equivalent non-zero number. Augmentation or division of the two sides of the condition by a similar articulation.
