Formula & Methodology
The square root of a number ‘n’, denoted as √n, is a value that, when multiplied by itself, gives the original number. Mathematically, this is expressed as:
√n = m, where m * m = n
Real-World Examples
Example 1: Distance Calculation
In physics, the distance between two points (x1, y1) and (x2, y2) can be found using the formula: √[(x2 – x1)² + (y2 – y1)²].
Let’s say we have two points (3, 4) and (-1, 2). Plugging these values into the formula gives us:
√[(-1 – 3)² + (2 – 4)²] = √(16 + 4) = √20 ≈ 4.47
