    I just did a C2 past paper from 2005, and the mark scheme says:

    "A1 an exact expression for x that can be evaluated on a calculator
    e.g. log35 scores M1 A0"

    However my calculator lets me evaluate log35 and gave me the right answer?

    When I bought it last year or the year before (can't remember exactly) it said on the box it was suitable for A level exams

    Your calculator, which I am assuming is the basic FX83GT, will always be suitable for exams. Please excuse me if I got the model wrong, please correct me if I am. But to my knowledge, what that mark scheme is saying is basically you showing no working out and completing an expression for x without specifying what you are doing on the paper.

    I apologize in advance if I am wrong, but that is what I think it means.

    You don't need to worry about this. The \log_a b function on your calculator can be used in modern exams.

    Thank you

    The question is 3^x = 5
    Find x

    I don't understand why it is not showing your working to say that the log of 3 which gives 5 is x. Isn't that what logarithms are?

    I don't get why you would need to say x = log 5 / log 3 (which is what the exam paper says I haven't done), that seems like an extra step for no reason?

    And yes that's my calculator!

    In those days the assumption was that calculators could only do log base 10 so certain mark schemes would only allow methods that used log base 10 caclulator function (this does seem silly looking back).

    If you look at any modern mark scheme you'll see alternative methods given that include the use of the \log_a b function.

    Oh alright

    Scary to think how much life has changed since the olden days of 2005!
