    When trying to input the equation into my calculator, I did log then 2 then multiply that by 16 but I got 4.8 instead of 4.

    I then came across this website which actually has the Log2 function built into it, and it gives me the right answer. So my question is, how can I replicate this function into my scientific calculator which lacks it :o:

    Log 2 is not the same as log (little 2). Sorry, i dont know how to do subscript

    Basically:

    Log (little Q) (P) =  \frac {log P}{log Q}

    Therefore here, you will type into your calculator, log 16 / log 2

    Also, the log on your calculator is log (little 10) as in, log to the base 10.

    Some scientific calculators have a \log _x y button. If yours doesn't, you need to use the following relationship between logs: \log _{2} x = \frac{\log _{10} x}{\log _{10} 2}. You calculator will have a \log _{10} button (which is often written as lg).

    Presumeably you have a log base 10 button.
    If so, use:

    log(16)/log(2)

    log_ax \equiv \frac {log_2x}{log_2a}

    Thanks, took me ages to sum up the courage of asking this rather embarrassing question!
