State if the number is real or non-real. If real also state if the number is rational or irrational: \( \sqrt{25} \)

The number \( \sqrt{25} \) is a real number because it equals 5, which is a number that can be found on the number line. Since 5 can be expressed as a fraction (for instance, \( \frac{5}{1} \)), it is also classified as a rational number. Another interesting point is that any perfect square, like 25, has a clean square root. When you encounter non-perfect squares (like \( \sqrt{2} \) or \( \sqrt{3} \)), those results are irrational numbers, as they cannot be expressed as a simple fraction. So, perfect squares like 25 always yield nice rational roots!
