Answer:
The solution that I am getting when simplifying this expression is
[tex]\sqrt{3} (x+3)^{\frac{1}{4} }[/tex] which is also [tex](\sqrt{3}) \sqrt[4]{x+3}[/tex] As this is not one of the options I can only assume that there was a part of the answer that you were not able to write. If this is not the case, feel free to delete this response.
Step-by-step explanation:
First, I'd like to confirm that I have the right information
Expression: [tex]\sqrt{3\sqrt{x+3} }[/tex]
a. [tex](3+x)\sqrt{3}[/tex]
b. [tex]2x\sqrt{3}[/tex]
c. [tex]3+x\sqrt{3}[/tex]
[tex]\sqrt{3\sqrt{x+3} }\\\\\sqrt{3} (\sqrt{\sqrt{x+3} } )\\\\\sqrt{3} (x+3)^{\frac{1}{4} }[/tex]
