title: Construct grammar given the following language {a^n b^m | n,m = 0,1,2,...,n <= 2m}
body: <p>I just took my midterm but couldn't answer this question.   </p>
  
  <p>Can someone please give a couple of examples of the language and construct a grammar for the language <strong>or</strong> 
  at least show me how i will go about it?</p>
  
  <p>Also how to write grammar for <code>L</code>: </p>
  
  <blockquote>
    <p>L = {a<sup>n</sup> b<sup>m</sup> | n,m = 0,1,2,..., n &lt;= 2m }   ?</p>
  </blockquote>
  
  <p>Thanks in advance.</p>
