The value of the common logarithm is undefined at 0.
The logarithm of 22.15 can be calculated using a scientific calculator or logarithm tables. For base 10 (common logarithm), the value is approximately 1.345. If you need the natural logarithm (base e), it is about 3.086. The specific value depends on the base you are using for the logarithm.
Yes, a logarithm can equal zero. Specifically, the logarithm of 1 is always zero, regardless of the base, because any number raised to the power of zero equals one (e.g., ( \log_b(1) = 0 ) for any base ( b > 0 )). Thus, ( \log_b(x) = 0 ) when ( x = 1 ).
Zero, in logs to base 10, base e, or any base.
The base b logarithm of x is a value y such that by = x
I am not quite sure what you mean with "log you"; the log is calculated for numbers. The following logarithms are undefined: For real numbers: the logarithm of zero and of negative numbers is undefined. For complex numbers: the logarithm of zero is undefined.
I suppose you mean log21 - the logarithm of 1, to the base 2. The logarithm of 1 (in any base) is zero, since x0 = 1 for any "x".

A number for which a given logarithm stands is the result that the logarithm function yields when applied to a specific base and value. For example, in the equation log(base 2) 8 = 3, the number for which the logarithm stands is 8.

The Logarithm of a number is the converse of its logarithmic value..
determination of log table value
In the real numbers, the logarithm is only defined for positive numbers. The logarithm of zero or a negative number is undefined. (For calculators who work with complex number, only the logarithm of zero is undefined.) This follows from the definition of the logarithm, as the solution of: 10x = whatever "Whatever" is the number of which you want to calculate the logarithm. Since 10x is always positive, that means you can't find an "x" such that the power results in a negative number, or in zero. The same applies if you use a base other than 10, for example the number e = 2.718...
The actual calculations to get a logarithm are quite complicated; in most cases you are better off if you look the logarithm up in tables, or use a scientific calculator.
The logarithm of zero is defined as approaching negative infinity because logarithmic functions represent the exponent to which a base must be raised to produce a given number. As the input to the logarithm approaches zero from the positive side, the exponent needed to achieve that value becomes increasingly negative. Therefore, ( \log_b(0) ) tends toward negative infinity, indicating that no finite exponent can result in zero when using positive bases.
