Answer:

12i\sqrt{11}

Step-by-step explanation:

Simplify:

Split the radical into two factors with a perfect square as at least one factor

4\sqrt{9} \sqrt{-11}

Evaluate the perfect square

4(3)\sqrt{-11}

12\sqrt{-11}

Since we cannot have a negative in a radical we need to factor out \sqrt{-1} which is represented as i

12i\sqrt{11}
