3 <p>If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in the field of vehicle design, finance, etc. Here, we will discuss the square root of 9/100.</p>

4 <h2>What is the Square Root of 9/100?</h2>

5 <p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. 9/100 is a<a>perfect square</a>.</p>

6 <p>The square root of 9/100 can be expressed in both radical and fractional form.</p>

7 <p>In the radical form, it is expressed as √(9/100), whereas, in fractional form, it is (3/10).</p>

8 <p>√(9/100) = 0.3, which is a<a>rational number</a>because it can be expressed in the form of p/q, where p and q are<a>integers</a>and q ≠ 0.</p>

9 <h2>Finding the Square Root of 9/100</h2>

10 <p>The<a>prime factorization</a>method is often used for perfect square numbers.</p>

11 <p>Let's learn how to find the<a>square root</a>of a<a>fraction</a>using the following methods: </p>

12 <ul><li>Prime factorization method</li>

13 <li>Simplification method</li>

14 </ul><h2>Square Root of 9/100 by Prime Factorization Method</h2>

15 <p>The<a>product</a>of prime<a>factors</a>is the prime factorization of a number.</p>

16 <p>Now let us look at how 9/100 is broken down into its prime factors:</p>

17 <p><strong>Step 1:</strong>Finding the prime factors of 9 and 100.</p>

18 <p>Breaking them down, we get 3 x 3 for 9 and 2 x 2 x 5 x 5 for 100.</p>

19 <p><strong>Step 2:</strong>We found out the prime factors of 9 and 100. The next step is to take the square root of each number. Since 9 is 3 x 3, its square root is 3. Since 100 is 2 x 2 x 5 x 5, its square root is 10.</p>

20 <p>Therefore, the square root of 9/100 is 3/10 or 0.3.</p>

40 <p>The area of the square is 0.09 square units.</p>

42 <h3>Explanation</h3>

41 <h3>Explanation</h3>

43 <p>The area of the square = side².</p>

42 <p>The area of the square = side².</p>

44 <p>The side length is given as √(9/100).</p>

43 <p>The side length is given as √(9/100).</p>

45 <p>Area of the square = side² = √(9/100) x √(9/100) = 0.3 × 0.3 = 0.09.</p>

44 <p>Area of the square = side² = √(9/100) x √(9/100) = 0.3 × 0.3 = 0.09.</p>

46 <p>Therefore, the area of the square box is 0.09 square units.</p>
