# Square Root Extraction Tool

Extraction of square root refers to finding the square root of a number in mathematics. The square root is a value that, when multiplied by itself, gives the original number. For instance, the square root of 9 is 3 because 3 * 3 = 9. The process of extracting square roots enables us to find what number multiplied by itself results in a given number.

Mathematically, the symbol √ represents the square root of a number. For example, √9 = 3 and √25 = 5. The extraction of square root is widely used in geometry, physics, engineering, and mathematics to solve numerical problems.

## What is the square root of 2?

The square root of 2 (√2) is approximately 1.4142135623730951. The square root represents a value that, when multiplied by itself, equals the given number. √2, which is approximately 1.4142135623730951, is an approximate value because the exact square root value of 2 cannot be expressed as a finite fraction or a terminating decimal. The fractional expression of the square root of 2 is an infinitely long decimal. Hence, √2 is commonly used as an approximate value.
