.htaccess URL rewrite with no query string variables

I have to rewrite the following URLs, can someone please suggest the contents of a .htaccess file that will do this.

For example:

example.com/retrieve_cat.php?subcat=364&c=134

example.com/category/subcategory/

Is it possible to rewrite this?
