3 times the square root of 5

It is 2*sqrt(5).

Find the prime factorization of the number left underneath the root, and if there are now repeated numbers, then the square root has been simplified completely. For example for 12√(30), the prime factorization of 30 is 2*3*5. There are no repeated numbers, so 12√(30) has been simplified completely. For 9√(50), the prime factorization of 50 is 2*5*5. A number is repeated (there are two 5's) so 9√(50) has not been simplified completely. (It can be simplified to 45√(2).)
