What is 3 square root 28 simplified?

Oh, what a happy little math question we have here! To simplify 3√28, we first look for the largest perfect square that divides evenly into 28, which is 4. So, we can rewrite 28 as 4 * 7. Now, we can take the square root of 4, which is 2, and bring it outside the square root symbol. This gives us 2 * √7, which is the simplified form of 3√28. Happy mathing, my friend!
