Solve the following python programming problem given the following code:
def _rewrite_inversion(fac, po, g, x) : 
    ' Absorb ``po`` == x**s into g. ' 
    (_, s) = _get_coeff_exp (po, x) 
    (a, b) = _get_coeff_exp (g.argument, x) 
    def tr(l) : 
        return [(t + (s / b)) for t in l] 
return (powdenest ((fac / (a ** (a / b))), polar = True), meijerg (tr (g.an), tr (g.aother), tr (g.bm), tr (g.bother), g.argument)) 

    
    

    Fix the buggy line: return (powdenest ((fac / (a ** (a / b))), polar = True), meijerg (tr (g.an), tr (g.aother), tr (g.bm), tr (g.bother), g.argument))
