I know that in an AC circuit at the steady state a capacitor behaves like a short and inductor behaves like an open. Since the inductor is open wouldn't that just mean the answer is 0?

No, those characteristics apply to DC steady state for those components. For AC, the components exhibit impedance that depends upon frequency.
