    Hi I was wondering what is the name/law given to the process of rewriting a logarithm into a exponential form? Some of the people in my class said its called the 'inverse log', others said its the 'anti log' and others called it the 'Rewrite as a power law' lol. Since our teacher hasnt been in for time I was just wondering if there is an actual name for this

    e.g log2(8) = 3 rewritten to give 2^3 = 8

    Thanks

    there is no name as far as I know.
    this is the definition of a logarithm

    I'd just say "writing it in exponent form" or perhaps "exponential form".

    Using words like inverse log and anti-log are surely only used to remind students of the relationship between them. I'd never actually call it either if those things.

    Google does throw up correct results for both 'anti-log' and 'inverse log', actually, but mainly with regard to just doing that stuff on a calculator. People might get what you mean, but certainly not necessarily straight away.

    So if I had a question where

    log_3 (\frac{y^2}{y+4}) = 2

    and then I had to do this to solve it

    \frac{y^2}{y+4} = 3^2

    \frac{y^2}{y+4} = 9

    y^2= 9(y+4)

    etc..

    I would say "I rewrote the equation in exponent form to get rid of the log function to be able to solve it"

    None of that anti/inverse log silly business?

    Precisely, as far as I'm concerned anyway.

    Reminding people that something is the inverse of something else can be useful. But I'd never say "anti-" anything in maths. I'm not American
