Definition of a Square Root
A square root is the value that, when multiplied by itself, gives the original number. In simpler terms, it is the number that, when squared, equals the given number. For example, the square root of 25 is 5 because 5 multiplied by itself equals 25.
How to Calculate a Square Root
Calculating a square root can be done manually or with the help of a calculator. For small numbers, you can use the prime factorization method or the long division method. However, for larger numbers, it is more practical to use a calculator or mathematical software.
To manually calculate a square root, you need to find the factors of the given number and pair them up. Take one factor from each pair and multiply them together until you reach a number that is less than or equal to the original number. This number is the square root.
Examples of Finding Square Roots
Let’s look at a few examples to illustrate how to find square roots:
Finding the square root of 9:
- Factors of 9: 1, 3, 9
- Pairing up factors: (1, 9) and (3, 3)
- Taking one factor from each pair: 3
- 3 multiplied by 3 equals 9, so the square root of 9 is 3.
Finding the square root of 16:
- Factors of 16: 1, 2, 4, 8, 16
- Pairing up factors: (1, 16), (2, 8), and (4, 4)
- Taking one factor from each pair: 4
- 4 multiplied by 4 equals 16, so the square root of 16 is 4.
Finding the square root of 36:
- Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
- Pairing up factors: (1, 36), (2, 18), (3, 12), and (4, 9)
