Calculation History

## What is Square Root?

The square root of a number is a value that, when multiplied by itself, gives the original number. In other words, it is the value that, when squared (multiplied by itself), equals the given number. The square root operation is denoted by the radical symbol (√) followed by the number whose square root is being calculated.

For example:

• The square root of 16 is √16 = 4 because 4 multiplied by 4 equals 16 (4 * 4 = 16).
• The square root of 25 is √25 = 5 because 5 multiplied by 5 equals 25 (5 * 5 = 25).

## All Formulae Related to Square Root

1. Basic Definition:

• Square root of a number (x): The number that, when multiplied by itself, equals x. It’s denoted by the symbol √x.

2. Basic Operations:

• Simplifying square roots: √(x * y) = √x * √y (if x and y are non-negative)
• Rationalizing denominators: To eliminate square roots from denominators, multiply both numerator and denominator by the same square root.

3. Properties of Square Roots:

• √x * √x = x
• √(x^2) = |x| (absolute value of x, because both x and -x, when squared, result in x^2)
• √(x/y) = √x / √y (if y is positive)

4. Pythagorean Theorem:

• In a right triangle, the square of the hypotenuse (the longest side) equals the sum of the squares of the other two sides: c^2 = a^2 + b^2
• Solving for a side: a = √(c^2 – b^2) or b = √(c^2 – a^2)

5. Distance Formula:

• The distance between two points (x1, y1) and (x2, y2) in a coordinate plane: d = √((x2 – x1)^2 + (y2 – y1)^2)

• The solutions to a quadratic equation ax^2 + bx + c = 0: x = (-b ± √(b^2 – 4ac)) / (2a)
