Answer 5

Hint

When it comes to problems like this, I like to replace the square root with a variable like so

\[\Large 5\sqrt{11}-12\sqrt{11}-2\sqrt{11}\]
\[\Large 5{\color{red}{\sqrt{11}}}-12{\color{red}{\sqrt{11}}}-2{\color{red}{\sqrt{11}}}\]
\[\Large 5{\color{red}{x}}-12{\color{red}{x}}-2{\color{red}{x}}\]
