connection to v is not important?
if i am doubt about your answer, how can i calculate it?
i connection to v is replaced with connection to constant voltage, then what's the impedance?
Incomplete problem description results in ambiguous or useless answer. At least one unclear point is floating substrate nodes.
Transconductance is a small signal quantity, respectively it's valid for a specific operation point only. Surely v must be connected to a constant voltage, also node I. You'll calculate the device currents and voltages for this operation point, get small signal conductances/impedances and know the answer.
As far as I see, M1 will be in ohmic mode and thus contribute to x node impedance.
