## How do you find the square root of 2 without a calculator?

Finding square roots of of numbers that aren’t perfect squares without a calculator

- Estimate – first, get as close as you can by finding two perfect square roots your number is between.
- Divide – divide your number by one of those square roots.
- Average – take the average of the result of step 2 and the root.

## Can the square root of 2 be simplified?

The square root of 2 is “irrational” (cannot be written as a fraction) because if it could be written as a fraction then we would have the absurd case that the fraction would have even numbers at both top and bottom and so could always be simplified.

## What is the square root of 2 used for?

Because √ 2 is not an integer ( 2 is not a perfect square ), √ 2 must therefore be irrational. This proof can be generalized to show that any square root of any natural number that is not the square of a natural number is irrational. Proof by Diophantine equations.

One even, another odd | Odd | Possible |

## How do you simplify?

To simplify any algebraic expression, the following are the basic rules and steps:
