  3.    base: base of the exponential, integer > 1
  4.    num: number you want to be closest to, integer > 0
  5.    Find the integer exponent such that base**exponent is closest to num.
  6.    Note that the base**exponent may be either greater or smaller than num.
  7.    In case of a tie, return the smaller value.
  8.    Returns the exponent.
