Question

When is written in simplest radical form, which value remains under the radical?

Answer 1

Answer:

The number that is a perfect square remains on the outside and the one that isn't, stays on the inside. For example, you can make the number 2$\sqrt{3}$ only when the number on the outside is a perfect square. The original number was 4, so it reduced down to 2, and the other number stayed in the radical
