If ( ( z ₁ )= (z₂ ) ), then

Options

  1. A( z ₂= kz ₁⁻¹( k > 0) )
  2. B( z ₂=k z ₁( k > 0) )
  3. C( |z₂ |= | z ₁ | )
  4. DNone of these

Correct answer

A. ( z ₂= kz ₁⁻¹( k > 0) )

Step-by-step solution

( aligned & z ₁= z₁ z ₁ z₁ = | z ₁ |^2 z ₁⁻¹ & ( z ₁⁻¹ )= ( z ₁ ) ( z ₂ ) & z ₂= kz ₁⁻¹( k > 0) aligned )
