Let’s solve each square root step by step. Remember: the
principal (positive) square root of a number is the positive number that, when multiplied by itself, gives you the original number.
We’ll go one by one:
---
√144 → What times itself = 144?
12 × 12 = 144 → So √144 =
12
√100 → 10 × 10 = 100 → √100 =
10
√25 → 5 × 5 = 25 → √25 =
5
√9 → 3 × 3 = 9 → √9 =
3
√4 → 2 × 2 = 4 → √4 =
2
√900 → Let’s think: 30 × 30 = 900 → √900 =
30
√121 → 11 × 11 = 121 → √121 =
11
√225 → 15 × 15 = 225 → √225 =
15
√64 → 8 × 8 = 64 → √64 =
8
√169 → 13 × 13 = 169 → √169 =
13
√81 → 9 × 9 = 81 → √81 =
9
√6400 → Think: 80 × 80 = 6400 → √6400 =
80
√625 → 25 × 25 = 625 → √625 =
25
√4900 → 70 × 70 = 4900 → √4900 =
70
√1 → 1 × 1 = 1 → √1 =
1
√196 → 14 × 14 = 196 → √196 =
14
√3600 → 60 × 60 = 3600 → √3600 =
60
√16 → 4 × 4 = 16 → √16 =
4
√49 → 7 × 7 = 49 → √49 =
7
√400 → 20 × 20 = 400 → √400 =
20
√1600 → 40 × 40 = 1600 → √1600 =
40
√2500 → 50 × 50 = 2500 → √2500 =
50
√8100 → 90 × 90 = 8100 → √8100 =
90
√36 → 6 × 6 = 36 → √36 =
6
