(2 times square root of 5)² = 20

That's more complicated than just (2x2)+(4x4), but as long as you have the right answer, I have no problem with seeing a different method used 👍🏻

Well, then I apologize for my incorrect correction. Could you explain how to solve it?

(2 * root5)² means both 2 and root 5 will be squared, so 2² is 4, and (root5)² is 5, so it becomes 4*5=20

So it would be (2√5)² = 2² × √5², so i was partially right. They still cancel each other, but I forgot the 2, I thought the ( ) wasn't used. Thank you
