Answer:
= - 12 + 316 i
Step-by-step explanation:
Given that -
z = 3 + i
<em>
= 
</em>
<em> = 9 + 
+ 6 i</em>
<em> = 9 - 1 + 6 i</em>
= 8 + 6 i
<em>
= × z</em>
<em> = ( 8 + 6 i ) × ( 3 + i )</em>
<em> = 24 + 8 i + 18 i + 6 i²</em>
<em> = 24 + 26 i - 6</em>
= 18 + 26 i
= ×
<em> = ( 8 + 6 i ) × ( 18 + 26 i )</em>
<em> = 144 + 208 i + 108 i + 156 i²</em>
<em> = 144 + 316 i -156</em>
= - 12 + 316 i
