    FX-100AU, Logarithms

    Hi all,

    I'm having trouble entering logarithms different to base 10.

    For instance, I want to type in \log_{2}16 and get the answer of 4.

    Any idea how to do this?

    Thanks folks.

    Hello Peleus,

    I don't think you can do it that way. I've not seen a calculator that allows you to enter a log to any base. Calculators generally have common "log" to base 10 or natural "ln" to base e. I think you will have to use the change of base formula and enter it this way:

    \frac{\log 16}{\log 2}=4 or \frac{\ln 16}{\ln 2}=4

    I hope that answered your question
