how to change url structure with 301 code q2a

问题

I have a problem with duplicate contents in search engine .

I can access a page in q2a web site using both of these url's !

http://www.domain.com/index.php?qa=1306&qa_1=title

http://www.domain.com/1306/title

I want to redirect the first one to second 1 how ca I do it ?

I tried codes in these page and other things too but none of them works :(

htaccess for changing index.php?ms=user to /user

my current htaccess is :

DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ index.php?qa-rewrite=$0&%{QUERY_STRING} [L]
# Redirect non-www to www:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
Redirect 301 /math/ http://math.domain.com/

</IfModule>
