How do you find square root of 14?

Answer 1

I can use various methods:

1. Using the square root button [√] on one of my electronic calculators (entering 14 as the number - before or after the [√] button depending upon which calculator it is I'm using)
2. Looking up 14 on the D or C scale of my slide rule and reading the square root off the A or B scale (respectively)
3. Looking it up in Square root tables
4. Finding the log of 14 (using calculator/slide rule/tables), dividing it by two and then finding the anti-log of the result.
5. A kind of long division as previously explained in other answers - search the web for: calculate square root by hand
6. Guess the square root of 14. Divide 14 by the guess. Add the result and the guess together and divide by 2 to give the new guess. Repeat with the new guess until the new guess is approximately the same as the old guess.
