godaddy and redirect

I have a godaddy domain with a wordpress blog. I am trying to move it from https://www.remax-best-kc.com/blog to remax-best-kc.com/ I have tried the godaddy redirect tool but does not seem to work, they are not very helpful, have tried the htaccess route but no luck. My htaccess file reads below. Any help on this is great. I want to preserve my page rank on the /blog site.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>

# END WordPress
