The square root of 25 is a fundamental concept in mathematics, particularly in the realm of algebra and geometry. To find the square root of 25, we need to determine the number that, when multiplied by itself, gives us 25. This is a basic operation in arithmetic, denoted by the symbol √.
Calculating the Square Root of 25
The calculation of the square root of 25 is straightforward. We know that 5 * 5 = 25. Therefore, the square root of 25 is 5. This can be expressed as √25 = 5. It’s worth noting that -5 * -5 also equals 25, so the square root of 25 can also be -5, denoted as √25 = ±5.
Understanding the Concept of Square Roots
Understanding square roots is crucial in mathematics, as they are used in various mathematical operations, including solving quadratic equations, calculating distances, and determining the area of shapes. The concept of square roots extends beyond simple arithmetic, into more complex areas of mathematics such as calculus and algebra.
| Number | Square | Square Root |
|---|---|---|
| 25 | 625 (25*25) | 5 (since 5*5=25) |
| 36 | 1296 (36*36) | 6 (since 6*6=36) |
| 49 | 2401 (49*49) | 7 (since 7*7=49) |
Key Points
- The square root of 25 is 5, since 5 * 5 = 25.
