How do you calculate the square root of a square number?

Answer 1

Answer: Type the number into your calculator... and hit the square root button.

Answer: To calculate with pencil and paper, several methods exist; all of them require some kind of iteration. Trial-and-error is the easiest, but not the fastest. Here is a fairly fast method: Estimate an initial square root. For example, estimate the square root of 2 as 1. Divide the number by the estimate; 2 / 1 = 2. Take the average of your prior estimate and the result of the division - in this case, 1.5. Repeat the method with this new number: 2 / 1.5 = 1.33333... Here, the new average is roughly 1.4. The number of correct digits approximately doubles every time you repeat the cycle.

Answer 2

you can use the square root button on a calculator. it looks like a long division ramp.

if you know the number and want to square it, just multiply it by it self.

example: i want to square six.

6x6=36

so, the square root of 36 is 6.
