Answer

$2 \sqrt{3}$

Work Step by Step

In order to simplify a radical, we consider the factors of the number inside of the radical. If any of these factors are perfect squares, meaning that their square root is a whole number, then we can simplify the radical. We know that 4 and 3 are factors of 12. We know that 4 is a perfect square, so we simplify: $ \sqrt{4} \sqrt{3}=2 \sqrt{3}$
