Product Model :

<?php

namespace App;

use IlluminateDatabaseEloquentModel;

class Product extends Model
{
    //
    public function categories()
    {
        return $this->belongsTo(Category::class);
    }
    public function sizes()
    {
        return $this->belongsTo(Size::class);
    }
}

Category Model :

<?php

namespace App;

use IlluminateDatabaseEloquentModel;

class Category extends Model
{
    //
    public function product()
    {
        return $this->hasMany(Product::class);
    }
    
}

Size Model :

<?php

namespace App;

use IlluminateDatabaseEloquentModel;

class Size extends Model
{
    //
    public function product()

        return $this->hasMany(Product::class);

In controller i am fetching data as below

public function productList()
    {
        $product = Product::get();
        $data = Product::with('categories','sizes')->get();
         return view('admin.productlist',['productdata' => $product ]);

<tbody id="example222">
                                    
                                    @foreach ($productdata as $product)
                                    {{$product}}
                                        <tr>
                                            <td>{{$product->product_name}}</td>
                                            <td>{{$product->categories}}</td>
                                            <td>{{$product->sizes}}</td>
                                            <td>{{$product->product_price}}</td>
