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 various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 4/49.</p>

4 <h2>What is the Square Root of 4/49?</h2>

5 <p>The<a>square</a>root is the inverse of the square of a<a>number</a>. 4/49 is a<a>perfect square</a>.</p>

6 <p>The square root of 4/49 can be expressed in both radical and<a>exponential form</a>.</p>

7 <p>In radical form, it is expressed as √(4/49), whereas in exponential form it is expressed as (4/49)^(1/2).</p>

8 <p>√(4/49) = 2/7, 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 4/49</h2>

10 <p>Finding the<a>square root</a>of a<a>fraction</a>involves taking the square root of the<a>numerator</a>and the<a>denominator</a>separately.</p>

11 <p>Since 4 and 49 are both perfect squares, we can use the simple method of finding their individual square roots:</p>

12 <p><strong>Step 1:</strong>Find the square root of the numerator, which is √4 = 2.</p>

13 <p><strong>Step 2:</strong>Find the square root of the denominator, which is √49 = 7.</p>

14 <p><strong>Step 3:</strong>Write the square root of 4/49 as the fraction of the square roots of the<a>numerator and denominator</a>, which is 2/7.</p>

15 <h2>Square Root of 4/49 by Prime Factorization Method</h2>

16 <p>The<a>prime factorization</a>method is used to find the square roots of numbers by breaking them into their prime<a>factors</a>.</p>

17 <p><strong>Step 1:</strong>Finding the prime factors of 4 and 49. Breaking down 4, we get 2 x 2: 2^2. Breaking down 49, we get 7 x 7: 7^2.</p>

18 <p><strong>Step 2:</strong>Since both numbers are perfect squares, we can find the square root by taking one of each pair of prime factors: √(4/49) = √(2^2 / 7^2) = 2/7.</p>
