However, others might use the notation $\log x$ for a logarithm base 10, i.e., as a shorthand notation for $\log_{10} x$. Because of this ambiguity, if someone uses $\log x$ without stating the base of the logarithm, you might not know what base they are implying. In that case, it's good to ask.

Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if b x = n, in which case one writes x = log b n. For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log 2 8. In the same fashion, since 10 2 = 100, then 2 = log 10 100.
