Answer:
[tex]6\sqrt{3} + 12[/tex] or [tex]6(\sqrt{3} +2)[/tex] when simplified.
Step-by-step explanation:
[tex](\sqrt{3} + 3)^{2}[/tex]
[tex](\sqrt{3} + 3)(\sqrt{3} + 3)[/tex] Multiply it out
[tex]3 + 3\sqrt{3} + 3\sqrt{3} +9[/tex] This is what you get, now add the roots together.
[tex]3+6\sqrt{3} +9[/tex] Then add the whole numbers together.
[tex]6\sqrt{3} + 12[/tex] This what you end with or you can simplify it.
[tex]6(\sqrt{3} +2)[/tex] This is what it looks simplified.
