Tinymce problem

When using subcripts and superscripts on extended tinymce plugin, they appear correctly on the preview but when a member views the post they appear as follows: x2 or x^2. The same thing you get when you copy equations from office word to notepad. Does anyone know how I can fix this? I would appreciate any form of help. Thanks
