3 <p>The square root of 26 is the inverse operation of squaring a value “y” such that when “y” is multiplied by itself → y ⤫ y, the result is 26. It contains both positive and a negative root, where the positive root is called the principal square root.</p>

4 <h2>What Is the Square Root of 26?</h2>

5 <p>The<a>square</a>root<a>of</a>26 is ±5.09901951359. The positive value, 5.09901951359 is the solution of the<a>equation</a>x2 = 26. As defined, the square root is just the inverse of squaring a<a>number</a>, so, squaring 5.09901951359 will result in 26. The square root of 26 is expressed as √26 in radical form, where the ‘√’ sign is called “radical” sign. In<a>exponential form</a>, it is written as (26)1/2 </p>

6 <h2>Finding the Square Root of 26</h2>

7 <p>We can find the<a>square root</a>of 26 through various methods. They are:</p>

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

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

10 </ul><ul><li>Approximation/Estimation method</li>

11 </ul><h3>Square Root of 26 By Prime Factorization Method</h3>

12 <p>The<a>prime factorization</a>of 26 involves breaking down a number into its<a>factors</a>. Divide 26 by<a>prime numbers</a>, and continue to divide the quotients until they can’t be separated anymore. After factorizing 26, make pairs out of the factors to get the square root. If there exists numbers which cannot be made pairs further, we place those numbers with a “radical” sign along with the obtained pairs</p>

13 <p>So, Prime factorization of 26 = 2 × 13 </p>

14 <p>for 26, no pairs of factors are obtained, but a single 2 and a single 13 are obtained.</p>

15 <p>So, it can be expressed as √26 = √(2 × 13) = √26</p>

16 <p>√26 is the simplest radical form of √26</p>
