In mathematics, the square of a number refers to the value which we get after multiplying the same number by itself. If Y x Y= X, then square root of X (√X) is equal to Y. Every non-negative number such as 1,2,3,4,5,… etc., can have a non-negative square root such √4=2,√9=3,√16=4, √25=5 etc.
A perfect square number such as 36 can have +6 and -6 as a square root, because (6)2 =36 and (-6)2 =36. This means that the square root of every square number can have both positive and negative value. Below is the table which shows square roots from 1 to 25 numbers:
| √4 | 2 | √225 | 15 |
| √9 | 3 | √256 | 16 |
| √16 | 4 | √289 | 17 |
| √25 | 5 | √324 | 18 |
| √36 | 6 | √361 | 19 |
| √49 | 7 | √400 | 20 |
| √64 | 8 | √441 | 21 |
| √81 | 9 | √484 | 22 |
| √100 | 10 | √529 | 23 |
| √121 | 11 | √576 | 24 |
| √144 | 12 | √625 | 25 |
| √169 | 13 | ||
| √196 | 14 |
Every non-negative number, if it is multiplied by itself, then the result is a square.
Just like the formulas of mathematics helps us to solve complex problems. Having a square root table handy will be useful while solving equations with speed and accuracy.
