If z= 4+ 7i be a complex number, then find
(i) Additive inverser of z.
(ii) Multiplicative inverse of z.

Explanation

To solve the problem, we will find the additive and multiplicative inverses of the complex number \( z = 4 + 7i \).

### Step 1: Find the Additive Inverse of \( z \)

The additive inverse of a complex number \( z \) is obtained by changing the sign of both the real and imaginary parts of \( z \).

Given:
\[
