Does anyone know any real-life applications of radical numbers? Are they used in any forms of real life?

Radical numbers? What do you mean? Irrational numbers like sqrt(2)? If so, they are used ALL the time. For example, if I tell you a ball is dropped to the Earth from a height of 20 meters, then it's height as a function of time is:

-4.9t^2 + 20 = 0

If you solve it for the time (t) it hits the ground, you get:
sqrt(392) / 9.8 which is an irrational number approximately equal to 2.02 seconds.

If you mean square roots by "radical numbers," then they are used all the time. Consider the pythagorean theorem, it is used extensively in similar triangles.

a real Example:
if you have a carpet with 2x1 dimensions, then the internal cross lines are 5^1/2, it means we you have aradical number in real.
