Square Roots (√):

We’re looking for the number that, when multiplied by itself, gives the number under the root.

- 256 → 16 × 16 = 256 → 16
- √4 → 2 × 2 = 4 → 2
- √169 → 13 × 13 = 169 → 13
- √100 → 10 × 10 = 100 → 10

- √121 → 11 × 11 = 121 → 11
- √196 → 14 × 14 = 196 → 14
- √16 → 4 × 4 = 16 → 4
- √64 → 8 × 8 = 64 → 8

- √1 → 1 × 1 = 1 → 1
- √9 → 3 × 3 = 9 → 3
- √49 → 7 × 7 = 49 → 7
- 144 → 12 × 12 = 144 → 12

- √225 → 15 × 15 = 225 → 15
- √81 → 9 × 9 = 81 → 9
- 25 → 5 × 5 = 25 → 5
- √36 → 6 × 6 = 36 → 6

Squares (number²):

Multiply the number by itself.

- 11² = 11 × 11 = 121
- 13² = 13 × 13 = 169
- 14² = 14 × 14 = 196
- 10² = 10 × 10 = 100

- 12² = 12 × 12 = 144
- 1² = 1 × 1 = 1
- 15² = 15 × 15 = 225
- 6² = 6 × 6 = 36

- 9² = 9 × 9 = 81
- 3² = 3 × 3 = 9
- 4² = 4 × 4 = 16
- 16² = 16 × 16 = 256

- 8² = 8 × 8 = 64
- 7² = 7 × 7 = 49
- 5² = 5 × 5 = 25
- 2² = 2 × 2 = 4
