5 <p>The<a>square</a>root<a>of</a>9 is ±3, where 3 is the positive solution of the<a>equation</a>x2 = 9. Finding the square root is just the inverse of squaring a<a>number</a>and hence, squaring 3 will result in 9. The square root of 9 is written as √9 in radical form, where the ‘√’ sign is called the “radical” sign. In<a>exponential form</a>, it is written as (9)1/2 </p>
