# The Simple Answer: Finding the Square Root of 256

As we delve into the world of mathematics, there are certain concepts that we must be familiar with. One such concept is square roots. Simply put, a square root is a number that can be multiplied by itself to give the original number. For instance, the square root of 25 is 5 because 5 multiplied by 5 is 25. In this article, we will be focusing on the simplest way to find the square root of 256.

Before we dive into the solution, let’s discuss some basics. The symbol used to denote a square root is √. So when we see √256, we know that it refers to finding the square root of 256. Another important thing to note is that not all numbers have a whole number as their square root. For example, the square root of 7 is approximately 2.65.

Now, let’s get to finding the square root of 256. There are several methods to do this, but the simplest one involves using a calculator. All you need to do is enter 256 and then press the √ symbol on your calculator. The resulting answer will be 16. Voila! That’s it.

If you don’t have a calculator handy, don’t worry. We can still find the square root of 256 using an ancient method called long division. It may sound daunting, but it’s actually quite simple.

Firstly, we need to group the digits of the number into pairs from right to left. Since 256 has only three digits, we will add a zero at the beginning to make it four digits. The pairs will then be 25 and 60.

Next, we start with the leftmost pair, which is 25. We need to find a number that, when multiplied by itself, gives a product less than or equal to 25. That number is 5, because 5 multiplied by 5 is 25. We write 5 as the first digit of the square root.

Then, we subtract 25 from 25, which gives us 0. We bring down the next pair, which is 60, to get 060.

We now double the first digit of our current square root (which is 5) and place it at the bottom of the number we just brought down. This gives us 10. We then find the largest digit such that when we append it to the number 5 at the top and multiply it by itself, the product is less than or equal to 100. That number is 6, because 56 multiplied by 6 is less than or equal to 100. We write 6 as the next digit of the square root.

We now have 16 as the tentative value of our square root. We need to check whether this is indeed the correct answer. We do this by squaring 16 and checking whether the result is equal to the original number, which is 256. If it is, then 16 is the correct square root. If not, then we need to repeat the process with more digits.

Thankfully, in this case, 16 is the correct square root. We can also confirm this by using a calculator as we did before.

In conclusion, finding the square root of 256 is a simple process that can be accomplished with a calculator or by using long division. Knowing how to find square roots is an essential skill in mathematics and can be applied in other areas such as geometry and physics.
