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 16 is 4 because \( 4 \times 4 = 16 \). For numbers that aren't perfect squares, the calculator provides a decimal approximation.

Worked Examples

Let's look at a few examples to understand how the square root calculator works:

Example 1: Perfect Square

Find the square root of 25.

Calculation

\( \sqrt{25} = 5 \) because \( 5 \times 5 = 25 \)

Example 2: Non-Perfect Square

Find the square root of 10.

Calculation

\( \sqrt{10} \approx 3.162 \) because \( 3.162 \times 3.162 \approx 10 \)

Example 3: Large Number

Find the square root of 144.

Calculation

\( \sqrt{144} = 12 \) because \( 12 \times 12 = 144 \)

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, 4 and -4 are square roots of 16.
Can I find the square root of a negative number?: No, the square root of a negative number is not a real number. This calculator only works with positive numbers.
What if I enter a very large number?: The calculator will still work, but very large numbers might result in very small decimal approximations.
Is the result always exact?: No, the result is exact only for perfect squares. For other numbers, the calculator provides a decimal approximation.
Can I use this calculator for scientific calculations?: Yes, this calculator is useful for basic mathematical problems, geometry, and algebra.
