    In general log indicates log base e


    However in A level the standard is to use log as log10 and ln as the natural log

    As TenofThem said:
    - in real maths, "log" is taken to mean "log base e"
    - in school maths, "log" will be assumed to mean "log base 10" unless you define it otherwise.

    Once you get beyond basic questions, though, using "log" without specifying the base will become troublesome as you have to change the base to answer a lot of questions.
