Summing up impedance with Current Source?

I got one short question. When adding up the impedances that are in parallel, and there is a current dependent current source as of the elements, what would that current source be considered as? would i just leave it out?

The picture attached is the problem tat i am looking at. Thanks in advance!

Unfortunately - no.

Only independent current sources may be treated according the rule - current source as open circuit, when attempting to evaluate impedances / resistances.

You must analyse the circuit using Kirchoff's Laws or note some other shortcut.

For instance - If you wanted to find Zin you would write Zin=Vin/Iin.

Write down the equation for Iin first and you'll perhaps notice a simple relationship falls out for the current source part of the equation.
