Answer: 4 + 16i

<u>Step-by-step explanation:</u>

  (2 + 2i)(5 + 3i)

= 2(5 + 3i) + 2i(5 + 3i)      <em>combine the two factors by multiplication</em>

= 10 + 6i + 10i + 6i²         <em>distribute</em>

= 10 + 6i + 10i + 6(-1)       <em>substitute -1 for i²</em>    

=  4 + 16i                         <em>add like terms (6i + 10i) </em>
