1*   3 * 5* 7 * 9 * 11 = 1946 là sai

tk mk nha 

hihi <3 nhiều ạ !!!

k kia sai vì có các chữ số lẻ mà có 1 chữ số 5 nên có tận cùng là 5  mới đúng mà có tận cùng là 6 nên sai

                                                        Giải 

         Tích trên là sai . Vì khi 5 * với các số chẵn thì tích tận cùng sẽ là 0 , còn nếu 5 * với các số lẻ sẽ có tận cùng là 5 .

         Tích trên 5 * với các số lẻ mà tích chữ số tận cùng là 4 suy ra tích trên là sai .

               mình chắc chắn đúng 100% luôn 

                       mà bn gì ơi với nhá !!! ^-^

                         chúc may mắn 

Reading books is very relaxing.
