Answer: 6 and 7
Step-by-step explanation:
The first thing to do is to have square numbers starting from 1 and multiply them. For example
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 × 4 = 16
5 × 5 = 25
6 × 6 = 36
7 × 7 = 49
8 × 8 = 64
Then, we look for the squares that when we subtract the smallest from the biggest we have 13.
From the analysis above, the numbers are 49 and 36 as 49-36 = 13.
Hence 6 and 7 are the numbers as the squares of 6 and 7 are 36 and 49 respectively
