احسب the logarithm of a number to any base:
* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12
احسب with log(number,base):
When:
b y = x
Then the base b logarithm of a number x:
logb x = y
In order to احسب log-1(y) on the حاسبة, enter the base b (10 is the default value, enter e for e constant), enter the logarithm value y and press the = or احسب button:
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
logb(x × y) = logb(x) + logb(y)
logb(x y) = y × logb(x)
