To solve , we first calculate the squares: and . Then, we subtract these numbers: . Finally, we take the square root of 36, which is 6. So, the answer is 6!

This expression is a classic example of the Pythagorean theorem in action, where . In this case, you can think of 10 as the hypotenuse and 8 as one of the legs of a right triangle. Finding the missing leg using this formula is a real-world application often found in architecture and construction, ensuring structures maintain physical integrity!
