Study Notes
Radicals
- Radicals are mathematical expressions used to represent roots of numbers.
- The operation associated with radicals is root extraction.
- Finding the square root of a number means finding a value that, when multiplied by itself, equals the original number.
- For example, the square root of 25 is 5 because 5 * 5 = 25.
- Cube root refers to finding a number that, when multiplied by itself three times, equals the original number.
- The cube root of 64 is 4 because 4 * 4 * 4 = 64.
- Radicals are represented using the radical symbol (√) followed by the number inside the radical sign, which is called the radicand.
- For example, √25 represents the square root of 25.
