Hi, because 1/a^n is Power[a,-n] and k/a^n is Times[k,Power[a,-n]] it would be nonsense to store Times[1,Power[a,-n]] in the first case and Times[1,q__] simplify to Times[q] Regards Jens Miguel wrote: > I have spent work hours with this case. > > ToString[#,InputForm]&/@{1/a^2,2/a^2,3/a^2} > {a^(-2),2/a^2,3/a^2} > > When the numerator of a rational element is 1, the structure string is > diferent.
