How to solve square roots manually
WebFirst, start by guessing a square root value. It helps if your guess is a good one but it will work even if it is a terrible guess. We will guess that 2 is the square root of 12. In step two, we divide 12 by our guess of 2 and we get 6. In step three, we average 6 and 2: (6+2)/2 = 4 Now we repeat step two with the new guess of 4. So 12/4 = 3 WebThere is a fun method for calculating a square root that gets more and more accurate each time around: a) start with a guess (let's guess 4 is the square root of 10) b) divide by the guess (10/4 = 2.5) c) add that to the guess (4 + …
