title: Math.pow alternative "**" ES7 polyfill for IE11
body: <p>I'm trying to evaluate an expression which contains power, in string as <code>**</code>. i.e. <code>eval("(22**3)/12*6+3/2")</code>.The problem is Internet Explorer 11 does not recognizes this and throws syntax error. Which poly-fill I should use to overcome this? Right now I'm using <code>Modernizr 2.6.2</code>.</p>
  
  <p>example equation would be, </p>
  
  <pre><code>((1*2)*((3*(4*5)*(1+3)**(4*5))/((1+3)**(4*5)-1)-1)/6)/7
  ((1*2)*((3*(4*5)*(1+3)**(4*5))/((1+3)**(4*5)-1)-1)/6)/7*58+2*5
  (4*5+4-5.5*5.21+14*36**2+69/0.258+2)/(12+65)
  </code></pre>
  
  <p>If it is not possible to do this, what are the possible alternatives?</p>
