In real-life scenarios, radical expressions and equations play a crucial role in a variety of fields. Let's explore a few practical examples of how radicals are used:

1. Geometry: Radicals come into play when calculating the length of the hypotenuse of a right-angled triangle using the Pythagorean theorem. For example, if the lengths of the other two sides are represented by √5 and √3, the length of the hypotenuse can be found by adding the squares of these radicals and then taking the square root. 2. Physics: When dealing with concepts such as distance, time, and velocity, radical expressions often arise. For instance, calculating the displacement of an object with respect to time is frequently done using radical equations. 3. Finance: The concept of compound interest involves exponentiation, which can be represented using radicals. By understanding radical expressions, you can grasp the calculations behind compound interest and make informed financial decisions.
