Answer:
1 1
2 4
3 9
9 81
11 121
15 225
7 49
Explanation:
If we look The number on the left is squared to get the number on the right
1^2 = 1
3^2 = 9
11^2 = 121
So we can fill in the rest of the table
1^1 = 1
2^2 = 4
3^3 = 9
To go backwards we take the square root
The square root of 81 = sqrt(81) = 9
9^2 = 81
11^2 = 121
15^2 =225
The square root of 49 = sqrt(49) = 7
