$**Calculating the Value of $\sqrt{119}$: A Mathematical Approach**$

===========================================================

Introduction

In mathematics, calculating the value of a square root can be a challenging task, especially when dealing with non-perfect squares. The square root of a number is a value that, when multiplied by itself, gives the original number. In this article, we will explore the process of calculating the value of $\sqrt{119}$ , a non-perfect square.

Understanding Square Roots

A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. However, not all numbers have perfect square roots, meaning that they cannot be expressed as a whole number multiplied by itself. $\sqrt{119}$ is one such example.

Methods for Calculating Square Roots

There are several methods for calculating square roots, including:

Long Division Method: This method involves dividing the number by a series of perfect squares to find the square root.
Babylonian Method: This method involves making an initial guess and then repeatedly averaging the guess with the number divided by the guess.
Newton-Raphson Method: This method involves making an initial guess and then repeatedly applying a formula to improve the guess.

Calculating $\sqrt{119}$ using the Babylonian Method

The Babylonian method is a simple and effective way to calculate square roots. Here's how to apply it to $\sqrt{119}$ :

Make an Initial Guess: Start by making an initial guess for the square root of 119. A good starting point is to guess a number that is close to the square root of 119. For example, we can start with a guess of 10.
Calculate the Average: Next, calculate the average of the guess and the number divided by the guess. In this case, we would calculate the average of 10 and 119/10.
Repeat the Process: Repeat steps 1 and 2 until the guess is accurate to the desired level of precision.

Calculating $\sqrt{119}$ using the Newton-Raphson Method

The Newton-Raphson method is another effective way to calculate square roots. Here's how to apply it to $\sqrt{119}$ :
