The caret symbol, ^, stops hyperlinks working, a phenomenon usually seen in links to Wolfram Alpha.
The [description](hyperlink) form:
this works, produced by [this works](http://wolframalpha.com/input/i=3x+2x)
this doesn't, produced by [this doesn't](http://wolframalpha.com/input/i=3^x+2x)
The HTML anchor form:
this works, produced by <a href="http://wolframalpha.com/input/i=ex+2x">this works</a>
this doesn't, produced by <a href="http://wolframalpha.com/input/i=e^x+2x">this doesn't</a>
Can anything be done to fix it, or a work-around found?
