### Square Numbers & Square Roots of Numbers

1. 1. Finding Square Numbers & Square Roots of Numbers For more maths help & free games related to this, visit: www.makemymathsbetter.com
2. 2. To square a number, you have to multiply a number by itself. For example, 1 squared, which is written as 1² = 1 x 1 = 1
3. 3. To square a number, you have to multiply a number by itself. For example, 1 squared, which is written as 1² = 1 x 1 = 1 It can be shown in a diagram as:
4. 4. To square a number, you have to multiply a number by itself. For example, 1 squared, which is written as 1² = 1 x 1 = 1 It can be shown in a diagram as: 2 squared, which is written as 2² = 2 x 2 = 4
5. 5. To square a number, you have to multiply a number by itself. For example, 1 squared, which is written as 1² = 1 x 1 = 1 It can be shown in a diagram as: 2 squared, which is written as 2² = 2 x 2 = 4 It can be shown in a diagram as:
6. 6. 3 squared, which is written as 3² = 3 x 3 = 9
7. 7. 3 squared, which is written as 3² = 3 x 3 = 9 It can be shown in a diagram as:
8. 8. 3 squared, which is written as 3² = 3 x 3 = 9 It can be shown in a diagram as: And 4 squared, which is written as 4² = 4 x 4 = 16
9. 9. 3 squared, which is written as 3² = 3 x 3 = 9 It can be shown in a diagram as: And 4 squared, which is written as 4² = 4 x 4 = 16 It can be shown in a diagram as:
10. 10. The square root of a number, written as √, is the opposite of the square of a number.
11. 11. The square root of a number, written as √, is the opposite of the square of a number. Therefore, the square root of 1, written as √1, is 1 as 1² = 1
12. 12. The square root of a number, written as √, is the opposite of the square of a number. Therefore, the square root of 1, written as √1, is 1 as 1² = 1 The square root of 4, written as √4, is 2 as 2² = 4
13. 13. The square root of a number, written as √, is the opposite of the square of a number. Therefore, the square root of 1, written as √1, is 1 as 1² = 1 The square root of 4, written as √4, is 2 as 2² = 4 The square root of 9, written as √9, is 3 as 3² = 9
14. 14. The square root of a number, written as √, is the opposite of the square of a number. Therefore, the square root of 1, written as √1, is 1 as 1² = 1 The square root of 4, written as √4, is 2 as 2² = 4 The square root of 9, written as √9, is 3 as 3² = 9 And the square root of 16 written as √16, is 4 as 4² = 16
15. 15. The square root of a number, written as √, is the opposite of the square of a number. Therefore, the square root of 1, written as √1, is 1 as 1² = 1 The square root of 4, written as √4, is 2 as 2² = 4 The square root of 9, written as √9, is 3 as 3² = 9 And the square root of 16 written as √16, is 4 as 4² = 16
