Unlock the power of logarithmic calculations with our Logarithm Calculator. Effortlessly determine logarithms of various bases and values.
* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12
Calculation with log(value,base):
When:
b y = x
Then the base b logarithm of a number x:
log b 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:
When
y = log b x
The anti logarithm (or inverse logarithm) is calculated by raising the base b to the logarithm y:
x = log b -1( y) = b y
logb(x × y) = logb(x) + logb(y)
logb(x y) = y × logb(x)
To calculate logarithms using the Logarithm Calculator, simply input the base and the value for which you want to find the logarithm. Click the "Calculate" button, and the calculator will provide you with the result. It's a quick and efficient way to determine logarithmic values.
