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.
In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.
An equation that contains a radical with a variable in the radicand is called a radical equation. These equations typically involve square roots, cube roots, or higher roots, and the variable is located inside the radical symbol. Solving radical equations often requires isolating the radical and then raising both sides of the equation to an appropriate power to eliminate the radical.
A radical number is a number that can be expressed as the root of an integer, typically involving square roots, cube roots, or higher roots. For example, √2 and ∛5 are radical numbers because they represent the square root of 2 and the cube root of 5, respectively. Radical numbers can be either rational (if the root results in a whole number) or irrational (if the root does not result in a whole number).
Radical signs, represented by the symbol √, indicate the square root or other roots of a number. The principal square root is the non-negative root, while the radical sign can denote higher roots, such as cube roots (∛). Simplifying radical expressions involves factoring out perfect squares or cubes from under the radical. Additionally, radical expressions can be added, subtracted, multiplied, or divided, following specific rules for combining radicals.
The answer depends on "different from WHAT?" Positive cube roots, or negative square roots?
it the number that is simfilied
an alg expression involving square roots, cube roots, etc

If by "radical" you mean "square root of", then yes. Both square roots of 25 are real numbers.
In the context of mathematics, "O" typically refers to the set of all ordered pairs or can represent a point in geometry, but it is not typically classified as a radical. A radical usually refers to an expression involving roots, such as square roots or cube roots. If you are referring to "O" in a different context, please provide more detail for a more accurate answer.
Simplest radical form means simplifying a radical so that there are no more square roots, cube roots, 4th roots and such left to find. It also means removing any radicals in the denominator of a fraction.
