# How do you find the square root of 8?

## Answer

###### Wiki User

###### 05/31/2009

sqrt(8)

= sqrt(4) * sqrt(2)

= 2 * sqrt(2)

= 2 * 1,4142

2,8284(..)

To calculate the square root of 2 I needed a calculator.

This number is irrational (you can prove that) which means there is no repeating part in the decimals of the square root of 2, and not in the square root of 8 either.
