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.
