Answer 1

Answer:

example

|z|2 = x2 + y2

Similarly, we have

|w|2 = u2 + v2

and, since zw = (xu – yv) + (xv + yu)i,

|wz|2 = (xu – yv)2 + (xv + yu)2

So, in order to show |zw|2 = |z|2|w|2, all you have to do is show that

(xu – yv)2 + (xv + yu)2 = (x2 + y2) (u2 + v2)

and that’s a straightforward exercize in algebra.
