What is the term for the argument in a logarithm function?

  1. Oct 6, 2011 #1
    If I have log a b = c, what is the term for the value b? I know that a is the base and c is the exponent, but I can't think of what b is called! While I am at it, in ab = c, what exactly is c called? The power? Would that make b from the previous example the power as well? I have a feeling that it is not called power since power is sometimes used for exponent.

    I don't see anywhere on that page that it answers swampwiz's question.

    Swampwiz, the only term I have ever heard used is exactly what you use- the "argument" of the logarithm.

    Hhhhmmm....oops, I guess you're right...they do mention the other two terms and their names, but not exactly that one...my mistake.
