The idea is to factor 2205 into two numbers where one is a perfect square. Then we use the rule sqrt%28x%2Ay%29=sqrt%28x%29%2Asqrt%28y%29


sqrt%282205%29+=+sqrt%28441%2A5%29 Notice how 441 is a perfect square (441 = 21^2)

sqrt%282205%29+=+sqrt%28441%29%2Asqrt%285%29

sqrt%282205%29+=+sqrt%2821%5E2%29%2Asqrt%285%29

sqrt%282205%29+=+21%2Asqrt%285%29
