A radical (√) is a symbol used to symbolize the square root of a number. For example, √4 would be read as "the square root of four," which can be simplified to 2. In cases where the resulting number is not a whole number, e.g. √5, it is sometimes the case that the number remains in that form for the final answer, depending on the problem and solution.

That depends on what math operation you are doing with them.
That depends on the type of problem. For example, if you have equations involving radicals, it often helps to square both sides of the equation. Note that when you do this, you may introduce additional solutions, which are not solutions to the original equation.
When adding and subtracting radicals, you can only combine radicals with the same index and radicand (the number inside the radical). Here are some examples:
electronegative radicals are anions or acid radicals.
In the game of DAMATH (an educational board game that combines math and checkers), the best move for radicals would depend on the specific game situation. Generally, it is advantageous to strategically place radicals in positions that allow for multiple capturing opportunities in subsequent turns. Additionally, positioning radicals in a way that disrupts the opponent's pieces or creates a defensive barrier can also be a strong move. Ultimately, the best move for radicals in DAMATH is one that maximizes control of the board and sets up future advantageous positions.
