Answer 1

You don't pass the product to the view. You need to compact the variable like this in the controller:
public function show($id)
{
$product = Product::findOrFail($id);
return view('shop.show', compact('product'));
}

Answer 2

you are getting product from database in $product variable, but not passing that variable to your view. There are several ways to pass variables to view.
return view('shop.show', compact('product'));
OR
return view('shop.show', ['product' => $product]);
OR
return view('shop.show', get_defined_vars());
get_defined_vars() is built-in php function, by using this function any numbers of variables declared in method, all will be passed to view
