I tried to Solve it And got the final expression as \[\frac{ 62i }{ 86i }\] Do I apply the modulus now ?

First find z1z2 and z1 z2 Then take the modulus of both and divide

I moreover simplified it to \[3i/43i\]

Now find modulus of 3i and find modulus of 43i and divide both

Taking a conjugate would help ?

multiply numerator and denominator by 4+3i it will make the problem more easier

@niksva This is what we call a conjugate and i was asking that only ?

Answer is \[\frac{\sqrt {10}}{5}\] What did you get?

@hba i know what is meant by conjugate i m telling u to rationalize the function

\[2\sqrt{2}/7\]

You made a mistake here. Let me show \[3i/43i\] \[3i=\sqrt{(3)^2+(1)^2}=\sqrt{10}\] \[43i=\sqrt{(4)^2+(3)^2}=\sqrt {25}=5\] so you'd get \[\frac{\sqrt{10}}{5}\]
