class_docstr: Represents ordinal exponential and multiplication terms one of the
  building blocks of the :class:`Ordinal` class.
  In ``OmegaPower(a, b)``, ``a`` represents exponent and ``b`` represents multiplicity.
code: def _compare_term(self, other, op):
      if self.exp == other.exp:
          return op(self.mult, other.mult)
      else:
          return op(self.exp, other.exp)
  
imports: from sympy.core import Basic, Integer
  import operator
label_desc: Use image node_id 4 for calling the OmegaPower obj's underlying member method code with example usage: obj._compare_term(other, op) and returns: op, op
