Redirecting visitors to root

So here is what I think should be a common problem but apparently is not. I have wordpress installed in its own directory. After some time I decided that instead of https://www.example.com/wordpress; it makes better SEO sense to have https://www.example.com

I followed the steps of the codex and everything works fine. However I have a lot of repeat visitors who have bookmarked https://www.example.com/wordpress

How do I automatically redirect them to the root? i.e. https://www.example.com

Mind you, since I have used the codex there are 2 index.php files and 2 .htaccess files (one set each in the root and wordpress folders).

The only thing that worked was this –

Redirect permanent /wordpress https://www.example.com/
Redirect 301 /wordpress/ https://www.example.com/

When I added this code to the .htaccess file in the /wordpress folder ; visitors get redirected fine. However images are broken and so is the theme since all that data is stored inside the wp-content folder inside the /wordpress/ (which is also getting redirected I think).

How do I redirect only the visitors? Please help.
