Square root is a reverse calculation of square. quare root is often difficult to calculate.
Suppose a number called a, you can think of a number multiplied by the same number a. The number is, a x a, often notated as a2.
We say a2 is a square of a.
Now we consider the reverse calculation of square. That is, when a number b is given, to find a number c where b = c2. We notate as √b = c.
While calculating a square is relatively easy, calculating a squareroot is often a labor.
Here is a form for calculating a squareroot.
* Please do not enter a negative number. The formula above cannot handle the negative number.
* Mathematically, a number has two square roots, one is plus and the other is minus. On the formula above, it shows only the plus one.
