Taking the square root of both sides, \( n = \sqrt{625} = 25 \).

["Title: Mastering Square Roots: How to Solve ( n = \sqrt{625} ) with Confidence", "Understanding how to safely manipulate equations involving square roots is a fundamental skill in algebra that can simplify complex problems. One of the most common operations you’ll encounter is “taking the square root of both sides”—a key technique used to isolate variables in quadratic expressions. In this article, we’ll explore how to correctly solve the equation ( n = \sqrt{625} ) using this method, why it works, and common pitfalls to avoid.", "---", "### What Does ( n = \sqrt{625} = 25 ) Really Mean?", "At first glance, the equation ( n = \sqrt{625} = 25 ) appears straightforward. It tells us that the number ( n ) equals the positive square root of 625, which is 25. But why is this accurate, and how do we justify taking the square root of both sides in more complex scenarios?", "The square root symbol ( \sqrt{} ) refers only to the non-negative root. Since ( \sqrt{625} = 25 ), it follows logically that ( n = 25 ). You cannot say ( n = \sqrt{625} ) is two values—only ( n = 25 ) (when restricted to principal roots).", "---", "### How to Take the Square Root of Both Sides (and Why)", "Suppose you have a more complex equation like:\n[\nx^2 = 625\n]\nTo isolate ( x ), you take the square root of both sides:", "[\n\sqrt{x^2} = \sqrt{625}\n]", "The left side simplifies to ( |x| ), since squaring a number and then taking the root yields the absolute value. Thus:", "[\n|x| = 25\n]", "This means ( x = 25 ) or ( x = -25 ).

Forget the Non-Negative Constraint\n Confusing ( \sqrt{x} = \pm x ) is a common error. While ( x^2 = a ) implies ( x = \pm\sqrt{a} ), a standalone square root always returns the non-negative result.", "2. Skipping Details in Simplification\n Always simplify square roots fully. ( \sqrt{625} ) simplifies to 25—not an approximation—since 25² = 625.", "3. Overcomplicating Simple Equations\n Taking root “both sides” is unnecessary for clean equations like ( n = \sqrt{625} ).
