Perhaps you have bumped into this math symbol √ not knowing what it actually means. Or you have memorized the answer of some square roots, but without being able to explain what it is. It is actually not that difficult to understand.
Consider the following explanation and examples. Then, take a tour to MathWareHouse, an interesting free math web site that helps you with square roots.
Before solving any complicated radical problem, you need to understand what a square root is. Consider the following example:
Think of the number 4. That number squared is 16. And the square root of 16 gives us 4.
In brief, the Square root is the inverse math operation of squaring any number. A square number is a number you multiply by itself.
For example, the number 5 square is 25. But, what about if we wanted to start with number 25 and say what times itself is equal to twenty five? The answer will be 5. But what symbol tells you that? The symbol is radical √. When using this symbol, you are saying what squared is equal to 25? Of course, the answer is 35.
This is the essence of the square root symbol.
So, if you are asked to find the square root of a number, you are asked for a digit that multiplied by itself gives you that number.
How to solve Square Roots
To understand this math operation, you need to know that there are two types of square roots. The perfect square is when a number can be expressed as the multiplication of two equal numbers, as in the examples above: 4, 16, and 25. But there are also not perfect squares or irrationals as 5, 7, 11, etc. because there are no two equal numbers that multiply by themselves result in those numbers. For irrational, it would have infinite digits to express that root.
To solve square roots, it is a good idea to learn by heart at least the first perfect square roots, because they are simple to calculate.
The more we know, the easier it will be, there are easy multiplications that allow us to calculate easy roots, for example, if 20 x 20 is 400, the square root of 400 will be 20. Note this detail: when you multiply 20 x 20 you are multiplying 2×2= 4 and you are adding a zero of each number 20, then you will be left: 20 x 20 = 400, so the square root of 400 can be divided into two parts: we calculate the root of 4 (which is 2) and as the 400 has two zeros to the two we add to the right a single zero, i.e. we divide the number of zeros by two (this is when it is a square root, if it was a cubic root are divided by three).
Remember, this procedure can be applied when the number is quadratic, if we had 500 and wanted to get the square root this would not work us because 5 does not have an exact square root, we will get 26.067977 … (We could approximate 26.07) but for this case, we should use a calculator or algorithm that you can find on Mathwarehouse.
