<p>The<a>square</a>root is the inverse<a>of</a>the square of the<a>number</a>. 2.5 is not a<a>perfect square</a>. The square root of 2.5 is expressed in both radical and<a>exponential form</a>. In radical form, it is expressed as √2.5, whereas (2.5)^(1/2) in exponential form. √2.5 ≈ 1.58114, 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>
