  1. let x = 2391/3072 2.38*3.901/4.83
    log x = log (2391/3072 2.38*3.901/4.83)
    = log(2391) - log(3072) + log(2.38) + log(3.901) - log(4.83)
    = 0.17496
    x = 1.496

    my calculator answer: 1.496 to 3 decimals

    This is the kind of question I actually taught about 45 years ago.
    In those days we had Log-tables that were only correct to about 3 decimals.
    To do the question the way I typed it, I actually used my calculator to get the log values.
    Today, such a question would only have significance from a historical viewpoint.
    Are you still given log tables?
    If not, how does your teacher expect you to do this without tables?

    This type of question is similar to asking a carpenter today to build a piece of furniture without any power tools.
