I am suppose to come up with an real life example where radical expression might be used.I was just wondering if someone could look over my example and tell me if it sounds ok.

Imagine a right triangle ABC, where B is the right angle. Say you wanted to travel from point A to point C. The path A-B-C consisted of two paved roads. Path A-C was an unpaved dirt path. If you knew the distances AB and BC, using mapquest for example, you could calculate the distance of path A-C using the Pythogorean Theorem.

AC = sqrt (AB^2 + BC^2)

This would tell you how much shorter the path A-C is than path A-B-C.

IT sounds Ok as an example.

Surveying would be another example.
