Solving for i is outside the radical .

  • a=5+√3i
  • b=5-√3i

[tex]\\ \sf\longmapsto ab[/tex]

[tex]\\ \sf\longmapsto (5+\sqrt{3}i)(5-\sqrt{3}i)[/tex]

[tex]\\ \sf\longmapsto 5^2-(\sqrt{3}i)^2[/tex]

[tex]\\ \sf\longmapsto 25-3i^2[/tex]

  • i=√-1

[tex]\\ \sf\longmapsto 25-3(-1)[/tex]

[tex]\\ \sf\longmapsto 25+3[/tex]

[tex]\\ \sf\longmapsto 28[/tex]
