Full question

For the given z, verify the displayed identity.

Step-by-step solution

1. First write z and its conjugate. Only the imaginary sign changes.

   $$(4\times i+3,3-4\times i)$$

2. Conjugate a second time. Reversing the imaginary sign again restores the original.

   $$4\times i+3=4\times i+3$$

Answer

The final answer is shown below.
