I think it's 2√5. Because it has no perfect square root. So, you should find the factor of 20 with one perfect square. And that's 4,5. The perfect square here is the 4, the square root is 2. That's why the answer that I think is 2√5. The 5 number is still on the square root because it has no square root. That's why it was left on the square. I guess that's the answer. I don't think so. ^^
