<p>The<a>square</a>root is the inverse of the square of a<a>number</a>. 28.13 is not a<a>perfect square</a>. The square root of 28.13 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √28.13, whereas (28.13)^(1/2) is its exponential form. √28.13 ≈ 5.303, which is an<a>irrational number</a>because it cannot be expressed in the form of p/q, where p and q are<a>integers</a>and q ≠ 0.</p>
