Square Root of 4 - MathQuadrum

What is square root of 4? Let’s explore the exact steps how to find square root of a number based on the below example

Identify as a Perfect Square: Recognize that 4 is a perfect square. It can be expressed as 2×2.
Determine the Square Root. Since 2×2 = 4, the square root of 4 is 2. This is because the square root of a number is the value that, when multiplied by itself, gives the original number.

Representing the Square Root of 4 Mathematically

As a Simple Number: The square root of 4 is precisely 2, so it is written as 4 = 2.
Using the Radical Symbol: Although it’s not necessary for perfect squares, you can also represent the square root of 4 using the radical symbol: √4. However, since its square root can be exactly determined, it’s typically simplified to its integer form, which is 2.

No Need for Approximation: For rational square roots like that of 4, there’s no need for decimal approximations or the use of the approximation symbol (≈) because the square root of 4 is exactly 2.

In summary, for perfect squares such as 4, finding the square root is straightforward, and it is expressed as a simple integer. Therefore, 4 = 2.
