Impedances in a 5 element circuit

[gimak]

Homework Statement

Just help me with 18 b.

Homework Equations

V₁ = c₁I₁Z₁. Same for V_2,3,45. V = V1+V2+V3+V4+V5. V/I=Z=impedance.

The Attempt at a Solution

Maybe because of symmetry Z1=Z2 & Z3=Z4. Perhaps Z5 takes out one of the branches? Can I get a hint?

Trying to read your image gives me eyestrain, but if Z1=Z2 & Z3=Z4 then what is I5 ?

I would not assume anything is equal to another unless the problem explicitly says that

I am following up on what YOU said not what the problem statement said

Oh! I was just guessing. I forgot to tell you, I basically solve this using loop current method & current equalities. Here's a link to my teacher's answer if it'll help.

One more thing: I still don't know how they jumped from the 2nd to last line to the last line in this problem (in the answer I mean).
