title: Android : Square and square root sign
body: <p>I am creating an app where I need to show square root signs along with numbers. 
  E.g.</p>
  
  <pre><code>  /¯¯¯¯¯¯¯¯¯¯¯
  \/  (v^2) / T
  </code></pre>
  
  <p>I am also looking to show square of a number. 
  Can anyone help in displaying such text. This text comes from a database and can change.</p>
