Explanation:
We have , to simplify a complex expression . Basically a complex expression in the form a + ib , where i =
and is called iota.
Expression:

⇒

We know that the mod or modulus of a complex number in the form of
is represented by Z and Z =
. Computing mod of
as :
⇒

⇒

Putting value of
as
, we get:
