    log_5(8) = log_5(2^3) = 3 x log_5(2)

    thanks for the explanation, that is exzactly what i was looking for.......

    I have another question : If log b< 0, then what can be said about b?

    Is the (b) refering to base, or is this an understood base 10, of b

    the problem is if this is understood as log_10 (b) I dont see anyway (b) can be < 0

    Think about this.

    10^(-1) = 0.1

    So what is log_10 (0.1) ?

    The usual convention is that if the base is not given it is base 10.

    ahhh....... I see Log_10(.1) = -1

    I managed to completely abolish log's of fractions from my thought process..........😀

    thanks again
