imaginary number equation
In physics, I have come across two equations for impedance:
where
Does this mean that from:
then
??
so is this an alternative form of pythag or am I completely wrong??

No, I think you've omitted some modulus signs around z like this: |z|
If z=x+iy (where x and y are both real), then |z|2=x2+y2. As davros says, you appear to have lost a modulus sign somewhere: in general, it is not the case that sqrt(a2+b2)=a+bi.

As above, though it may be worth noting that
In general:
Where
Unparseable latex formula:
then:z = a+bi \ \ a,b \in \matbb{R}
