To calculate a square root by hand, first estimate the answer by finding the 2 perfect square roots that the number is between. A perfect square root is any square root that's a whole number.
Here are the steps to estimate the square root of a number n: Find a perfect square near n, and use its square root x as your first guess. If \ (x^2 > n\), make a new guess lower than x; if \ (x^2 < n\), make a new guess higher than x.
How to find the square root of a number and calculate it by hand. By Alexander Arobelidze. At times, in everyday situations, we may face the task of having to figure the square root of a number.

At first glance, the method used to manually calculate the square root of a number looks very similar to division by hand already explained in the first chapter. Let's explain how to find the square root step by step.
In just three easy steps, learn how to take the square root of any positive number, regardless of whether or not the result is rational! The long division method is fast, efficient, and not too...
Children today still learn how to add, subtract, multiply, and divide by hand, but 40 years ago children also had to learn to compute square roots by hand! If you want to revive an old skill, or are just mathematically curious, here are the steps to computing square roots by hand.
Estimating an n th Root. Calculating n th roots can be done using a similar method, with modifications to deal with n.While computing square roots entirely by hand is tedious. Estimating higher n th roots, even if using a calculator for intermediary steps, is significantly more tedious. For those with an understanding of series, refer here for a more mathematical algorithm for calculating n th ...
We can find square roots to any accuracy we wish by applying this method enough times. In fact, what we’re doing is applying a special case Newton’s root-finding method. We showed above that the error after each iteration is on the order of the square of the previous error.
Few people today feel the need to learn how to compute a square root by hand, preferring to entrust the tedious task to software or a pocket calculator, digital instruments that are now...
