The expression \( \sqrt{12} \) can be simplified by breaking it down into its prime factors.
\[ \sqrt{12} = \sqrt{4 \times 3} \]
Since \( \sqrt{4} = 2 \), we can simplify it further:
\[ \sqrt{12} = \sqrt{4} \times \sqrt{3} = 2\sqrt{3} \]
Thus, the simplified form of \( \sqrt{12} \) is:
\[ 2\sqrt{3} \]
