In this article, i will introduce another function in VB.NET regarding the Math Functions, the **Math.Sqrt()**. Math.Sqrt() function provides to compute the square root of a number. This will help the students to solve their quizzes and exams regarding how to get a square root of a number by only a manual solving. haha. LOL. :)

So, now let's start this tutorial!

1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to **File**, click **New Project**, and choose **Windows Application**.

2. Next, add two TextBoxes named **TextBox1** and **TextBox2** then leave it as blank. **TextBox1** will be your whole number as an input, and **TextBox2** will be the result of the square root you've input. Now, add a Button named Button1 to see the result of the Square Root and displayed in TextBox2. You must design your layout like this:

3. Now, put this code in Button1_Click. This will display the result of the square root in TextBox2.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim num1 As Integer End Sub

We initialized num1 as Integer to hold the value inputted in TextBox1. Then in TextBox2, we compute the square root of a number inputted in num1 with the syntax `Math.Sqrt(num1)`

. Math.Sqrt() Function is only for calculating the square root of number.

Download the source code below and try it! :)
