    Definition of log:

    Log (base b) (x) = y or equivalently

    if b^y = x then Log (base b) (x) = y

    Given 2^3=8

    set x=8, b=2, y=3

    take log (to base 2) on both sides, then

    log (base 2) 8 = 3

    Take the natural log of both sides:

    ln 2^3 = ln 8, or 3 ln 2 = ln 8, following rules of logs.
