Square Root Formula

The square root of a number \( x \) is a value that, when multiplied by itself, gives \( x \). Mathematically, this is represented as:

Square Root Formula

\( \sqrt{x} = y \) where \( y \times y = x \)

For example, the square root of 25 is 5 because \( 5 \times 5 = 25 \). The square root of 2 is approximately 1.414 because \( 1.414 \times 1.414 \approx 2 \).

Worked Examples

Example 1: Finding the Square Root of 16

To find the square root of 16:

  1. Enter 16 in the calculator input field.
  2. Click "Calculate".
  3. The result will show that \( \sqrt{16} = 4 \).

This is because \( 4 \times 4 = 16 \).

Example 2: Finding the Square Root of 3

To find the square root of 3:

  1. Enter 3 in the calculator input field.
  2. Click "Calculate".
  3. The result will show that \( \sqrt{3} \approx 1.732 \).

This is because \( 1.732 \times 1.732 \approx 3 \).

Frequently Asked Questions

What is a square root?
A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square roots of 9 are 3 and -3 because \( 3 \times 3 = 9 \) and \( -3 \times -3 = 9 \).
Can I find the square root of a negative number?
No, the square root of a negative number is not a real number. It is an imaginary number, which involves the square root of -1, denoted as \( i \). For example, \( \sqrt{-1} = i \).
How do I find the square root of a fraction?
To find the square root of a fraction, you can take the square root of the numerator and the denominator separately. For example, \( \sqrt{\frac{4}{9}} = \frac{\sqrt{4}}{\sqrt{9}} = \frac{2}{3} \).
What is the difference between a square root and a square?
The square of a number is the result of multiplying the number by itself. For example, the square of 5 is \( 5 \times 5 = 25 \). The square root is the inverse operation, finding a number that, when squared, gives the original number.
How accurate are the results from this calculator?
The calculator provides results rounded to 10 decimal places for precision. For most practical purposes, this level of accuracy is sufficient. However, for scientific or engineering applications, you may need more precise calculations.
