When multiplied by the same number, the square root is a numeral that gives the solution as the actual number. For example, the square root of 5 up to 7 decimal places is 2.2360679. Moreover, the square root of 5 is represented as 5. Thus, parents and teachers can introduce the 5 Times Table to kids, available at Osmo, alongside teaching them the concept of the square root of 5. It is a known fact that kids find it quite challenging to understand the concept of the square root of -5 and the square root of 5.
What is the Square Root of 5?
As mentioned above, the square root of 5 or any numeral gives the solution as the actual number when multiplied by itself. For instance, 5 x 5 = 25. In this example, 5 is the square root of 25 and 25 is considered the perfect square. But, 5 is a non square number and has a square root that is not a whole number. So, what’s the square root of 5? The square root of 5 is represented in 3 ways, such as,
- Decimal form: 2.236
- Radical form: 5
- Exponential form: (5)½ or (5)0.5
Also, the little ones can be introduced to Osmo’s Math Games for Kids.
How to Find the Square Root 5?
There are various methods to determine the square root of 5. However, the simplest and primary method to find the square root of 5 is the prime factorization method. Below given are the easy steps to find out the square root of 5.
- 5 x 5 = 1
- 5 = 5
Now, let us consider the square root
- 5 = 5
- 5 = 2.236
Once the little minds have learned this method of finding out the square root of 5, they can be introduced to another method of determining the square root of 5, that is, the long division method.
How to the Find Square Root of Negative 5?
It is possible to find the square root of negative 5 with the help of complex and imaginary numbers, i. Now, let us begin by considering the imaginary square root of negative 1. Here is how to find the square root of negative 5.
-5 = 5 x -1
Here, the square root of 5 is 2.236. And, the square root of negative 1 is an imaginary number. Thus, the solution to determining the square root of negative 5 is -5 = 2.235 i.
Is the Square Root of 5 Rational or Irrational?
Any number that is expressed as a ratio of 2 integers, that is p/q, p and q, where q is ≠ (unequal) 0 is known as a rational number. In this context, let us consider the number 25. 25= 5 = 5/1. Hence, 25is considered a rational number. Now, let us have a look into this case, the square root of 5.5 = 2.236. Any number that is not expressed in the form of a ratio of 2 integers is known as an irrational number. Therefore, the number 5 is not a perfect square and is an irrational number.
