Introduction

In mathematics, square roots are a fundamental concept that plays a crucial role in solving equations and manipulating expressions. When dealing with square roots, it's essential to understand how to simplify them to their most basic form. In this article, we will explore the process of simplifying square roots, focusing on the principal square root of both sides of an equation.

The Problem

Let's consider the equation $\sqrt{2a^2} = \sqrt{c^2}$ . Our goal is to simplify the expression $\sqrt{2} = \square$ .

Step 1: Take the Principal Square Root of Both Sides

To simplify the equation, we start by taking the principal square root of both sides. This means we remove the square root symbol from both sides of the equation.

$\sqrt{2a^2} = \sqrt{c^2}$

By taking the principal square root of both sides, we get:

$a\sqrt{2} = c$

Step 2: Simplify the Expression

Now that we have simplified the equation, we can focus on the expression $\sqrt{2} = \square$ . To simplify this expression, we need to find the value of $\square$ .

The Simplification Process

To simplify the expression $\sqrt{2} = \square$ , we need to find the value of $\square$ that makes the equation true. Let's assume that $\square = x$ . Then, we can rewrite the equation as:

$\sqrt{2} = x$

To simplify this equation, we can square both sides, which gives us:

$2 = x^2$

Solving for x

Now that we have squared both sides, we can solve for $x$ . To do this, we take the square root of both sides, which gives us:

$x = \pm \sqrt{2}$

The Final Answer

So, what is the value of $\square$ ? Based on our simplification process, we can conclude that:

$\square = \pm \sqrt{2}$

Conclusion

In this article, we explored the process of simplifying square roots, focusing on the principal square root of both sides of an equation. We started with the equation $\sqrt{2a^2} = \sqrt{c^2}$ and simplified it to $a\sqrt{2} = c$ . Then, we focused on the expression $\sqrt{2} = \square$ and simplified it to $\square = \pm \sqrt{2}$ . By following these steps, we can simplify square roots and find the value of $\square$ .
