LOGARITHMIC FUNCTION
The logarithm of a given number b to the base ‘a’ is the exponent indicating the power to which the base ‘a’ must be raised to obtain the number b. This number is designated as log a b. Hence log a b = x Û ax = b, a > 0, a1 and b>0. From the definition of the logarithm of the number b to the base ‘a’, we have an identity
This is known as Fundamental Logarithmic Identity.
