What is the square root 22?

Answer 1

Using a calculator, the square root of 22 is found to be 4.69041576. However, you can find an approximation without using a calculator: √ 22 = √ (44/2) = √ ((4*11)/2) = 2√ (11/2) = 2 √ 5.5 If you happen to know the square root of both five and six, than you can estimate the square root of 5.5. Alternatively, you could Find the square root of 11 and divide it by the square root of 2. The first method is probably easier. I would estimate the √ 5.5 at about 2.34, which when multiplied by 2 would equal 4.68, which is pretty close to the calculator answer.
