Radical two times radical two is equal to two. This is because when you multiply the square root of a number by itself, you get that number back. In this case, (\sqrt{2} \times \sqrt{2} = 2).
Radical 15 times radical 15 is equal to 15. When you multiply two square roots of the same number, you can simplify it as follows: √15 × √15 = √(15 × 15) = √225, which equals 15.
If the product of two irrationals is a rational, then they are both the same radical of a non-perfect square. For example, radical 5 times radical 5 is 5, since that is by definiton what a radical is.

The square root of 28 or in this case the radical form of 28 will be 2 times radical 7. Since 28 is 4 times 7 and the square root of 4 is two.
1 over 2 times radical 6
"Radical x times radical x" could be interpreted as the square root of x times the square root of x - in which case the product would be x (the number under the radical sign)
