false , i tried it on apex so its right

You can multiply the radicands together if the radical is the same. So, the answer is radical 13*17=radical 221

Radical like terms are expressions that contain the same type of radical, meaning they have the same index and the same radicand (the number or expression inside the radical). For example, ( \sqrt{2} ) and ( 3\sqrt{2} ) are like terms because they both involve the square root of 2. However, ( \sqrt{2} ) and ( \sqrt{3} ) are not like terms since their radicands differ. Like terms can be combined through addition or subtraction.

Radical expressions are called like radical expressionsif the indexes are the same and the radicands are identical.

No. For small radicands you can test the radical to see if it is rational. But for very large numbers it may not be simple and may even be impractical.
Multiplying the radicands of the two together, sqrt(2) x sqrt(15) is equal to sqrt(2 x 15) = sqrt(30).
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
