Undefined variable:

Bagaimana mengatasi "Undefined variable: produks3" ketika saya mau show 4 data pada satu template blade ?

controller

 public function index()
    {
    	$produks = DB::table('produks')->where('kategori_id', '4')->orderBy('kategori_id')->limit(3)->get();
    	$produks2 = DB::table('produks')->where('kategori_id', '4')->orderBy('kategori_id')->limit(3)->get();
    	$produks3 = DB::table('produks')->where('kategori_id', '5')->orderBy('kategori_id', 'desc')->limit(3)->get();
    	$produks4 = DB::table('produks')->where('kategori_id', '5')->orderBy('kategori_id', 'desc')->limit(3)->get();

    	return view ('welcome',['produks'=>$produks], ['produks2'=>$produks2], ['produks3'=>$produks3]);
    }

routes

 Route::get('/', 'HomeController@index');

template blade

  @foreach ($produks3 as $produk3)
                                <div class="col-md-4 agile_ecommerce_tab_left">
                                    <div class="hs-wrapper">
                                        <img src="{{ asset('storage/produk/' . $produk3->gambar) }}" alt=" " class="img-responsive" />
                                        <div class="w3_hs_bottom">
