Remove all tags in woo price output and get only value?

Question

WordPress

Hello, how can I remove all tags in the price display from the Woocommerce plugin?
<?php echo $product->get_price_html(); ?>
Outputs such a plan code

<span class="woocommerce-Price-amount amount">850&nbsp;<span class="woocommerce-Price-currencySymbol">грн.</span></span>

How to get clean 850 from it, that is, price?
