What is radical
Solution
In mathematics, a radical refers to the root of a number or expression, typically expressed using the radical symbol (√). The radical symbol is used to indicate roots, such as square roots, cube roots, or higher-order roots.
Key Points About Radicals:
-
Square Root (√): The most common radical, which represents a number that, when multiplied by itself, gives the original number. For example:
-
Cube Root (): Represents a number that, when multiplied by itself three times, gives the original number. For example:
-
Higher Roots: You can have fourth roots, fifth roots, etc., expressed as , where is the degree of the root.
-
Radical Expressions: A radical can involve variables, such as , which follows the same principles as numerical radicals.
-
Simplifying Radicals: Radicals can often be simplified by factoring the number under the radical into its prime factors or into perfect squares/cubes. For example:
