We are presenting the Logarithm calculator online to calculate the logarithm of any number with any base.
- Logarithm calculator
- Antilog calculator
All you need to do is simply enter the base b and any number x and finally press the = button.
**Use e for scientific notation.
When the value of b y = x
Then the value of base b logarithm of the number x, logb x = y
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.
The anti logarithm or the inverse logarithm can simply be calculated by raising the value of base b to the logarithm y.
When the value of y = logb x
x = logb-1(y) = b y
The Rule of Logarithm
Rule of Logarithm product
logb(x × y) = logb(x) + logb(y)
Rule of Logarithm quotient
logb(x / y) = logb(x) – logb(y)
Rule of Logarithm power
logb(x y) = y × logb(x)
Rule of Logarithm base switch
logb(c) = 1 / logc(b)
Rule of Logarithm base change
logb(x) = logc(x) / logc(b)
