Answer -
Here,
1 ×5 1= remainder obtained by dividing 1 × 1 by 5
= 1
3 ×5 4= remainder obtained by dividing 3 × 4 by 5
= 2
4 ×5 4= remainder obtained by dividing 4 × 4 by 5
= 1
So, the compositiontable is as follows:
| ×5 | 0 | 1 | 2 | 3 | 4 |
| 0 | 0 | 0 | 0 | 0 | 0 |
| 1 | 0 | 1 | 2 | 3 | 4 |
| 2 | 0 | 2 | 4 | 1 | 3 |
| 3 | 0 | 3 | 1 | 4 | 2 |
| 4 | 0 | 4 | 3 | 2 | 1 |
