Why can't I import my jQuery file correctly?

Question

I wanted to try JQuery for the first time,and I downloaded the "jquery-3.6.1.min"-file,which I saved in this directory:"C:\xampp\htdocs\php\Bücher\Jquery\jquery-3.6.1.min". I wanted to try it out,and I imported it into the html-file like this:

<script src="Bücher\Jquery\jquery-3.6.1.min.js">
            $(document).ready(function(){
                $('p.fr_para').html().fadeOut(700);
            });
</script>

(paragraph is like this:)

<p class = "fr_para" lang = "fr">Paragraphe en Français</p>

However for some reason nothing happened,I conclude,that I wrote my code wrong,but can't find what caused the error,can someone help me? Tkanks,everyone!

I don't know what to try,I installed JQuery and the syntax should be right,I don't know what I did wrong...
