3 <p>Let’s discuss what is a square root? The square root of a number is a number, when multiplied by itself gives the number. Radical symbol (√) is the symbol used to indicate square root. The square root of 25 is ±5. We use it in our daily life in physics, engineering, finance etc.</p>

4 <h2>What is the square root of 181</h2>

5 <p>In this article, the<a>square</a>root<a>of</a>181 is ±13.454. The square root of 181 is expressed as √181, in radical form. It is expressed as (181)½ in<a>exponential form</a>. </p>

6 <h2>Finding the square root of 181</h2>

7 <p>If a student wants to find the<a>square root</a>of a<a>number</a>. Which are the methods they can use? Some common methods are,</p>

8 <ul><li>Prime factorization</li>

9 </ul><ul><li>Long<a>division</a></li>

10 </ul><ul><li>Approximation</li>

11 </ul><ul><li>Subtraction method</li>

12 </ul><p>Let’s check the square root of 181 using these methods </p>

13 <h3>Square root of 181 by prime factorization</h3>

14 <p>In this method, all the<a>prime factors</a>of the number are listed down and then from there one number from each pair is listed down. Then the numbers are multiplied together. </p>

15 <p>By using prime factorization, let’s check out the square root of 181.</p>

16 <p><strong>Step 1:</strong>Listing out the prime factors of 181 and pairing the same numbers.</p>

17 <p>Prime factors of 181 = 1 × 181 </p>

18 <p>As 181 is a<a>prime number</a>, the prime factorization method is not applicable for the square root of 181.</p>

26 <p> Here the number is, because 12 = 1</p>

25 <p> Here the number is, because 12 = 1</p>

27 <p><strong>Step 2:</strong>So, let’s divide 1 by 1</p>

26 <p><strong>Step 2:</strong>So, let’s divide 1 by 1</p>

28 <p><strong>Step 3:</strong>Now, the<a>quotient</a>and<a>divisor</a>is 1, for the new divisor we add the divisor with itself.</p>

27 <p><strong>Step 3:</strong>Now, the<a>quotient</a>and<a>divisor</a>is 1, for the new divisor we add the divisor with itself.</p>

29 <p><strong>Step 4:</strong>Continue the process till the<a>remainder</a>is 0</p>

28 <p><strong>Step 4:</strong>Continue the process till the<a>remainder</a>is 0</p>

30 <p>The quotient will be the square root of the number.</p>

29 <p>The quotient will be the square root of the number.</p>

31 <p>Therefore, the square root of 181 is ±13.45 </p>

30 <p>Therefore, the square root of 181 is ±13.45 </p>

32 <h3>Square root of 181 by approximation</h3>

31 <h3>Square root of 181 by approximation</h3>

33 <p>Approximation method is mainly used for not a<a>perfect square</a>. As 181 is not a perfect square, the approximation method can be used to find the square root of 181. </p>

32 <p>Approximation method is mainly used for not a<a>perfect square</a>. As 181 is not a perfect square, the approximation method can be used to find the square root of 181. </p>

34 <p>Step 1: Find any two perfect squares numbers between which 181 lies. The two perfect squares are 132 (169)and 142 (196)</p>

33 <p>Step 1: Find any two perfect squares numbers between which 181 lies. The two perfect squares are 132 (169)and 142 (196)</p>

35 <p>Therefore, the square root of 181 lies between 13 and 14,<a>i</a>.e, 13 < √181 <14</p>

34 <p>Therefore, the square root of 181 lies between 13 and 14,<a>i</a>.e, 13 < √181 <14</p>

36 <p>Step 2: for checking out the<a>decimal</a>part, the<a>formula</a>is </p>

35 <p>Step 2: for checking out the<a>decimal</a>part, the<a>formula</a>is </p>

37 <p>Hence,181 - 169 /196 - 169 = 12/27 = 0.44</p>

36 <p>Hence,181 - 169 /196 - 169 = 12/27 = 0.44</p>

38 <p>So, the approximate square of 181 is ±13.44 </p>

37 <p>So, the approximate square of 181 is ±13.44 </p>
