Square Root of 25 + Solution With Free Steps

The square root of 25 is 5. You can write the number’s square root as √25= 5. We get 25 when we multiply the result by itself. √25 times √25 equals 25, which is equal to 5 times 5. 25 is a rational number.

In this article, we will analyze and find the square root of 25 using various mathematical techniques, such as the approximation method and the long division method.

What Is the Square Root Of 25?

The square root of the number 25 is 5.

The square root can be defined as the quantity that can be doubled to produce the square of that similar quantity. In simple words, it can be explained as:

√25 = √(5 x 5)

√25 = √(5)$^2$

√25 = ±5

The square can be canceled with the square root as it is equivalent to 1/2; therefore, obtaining 5. Hence 5 is 25’s square root. The square root generates both positive and negative integers.

How To Calculate the Square Root of 25?

You can calculate the square root of 25 using any of two vastly used techniques in mathematics; one is the Approximation technique, and the other is the Long Division method.

The symbol √ is interpreted as 25 raised to the power 1/2. So any number, when multiplied by itself, produces its square, and when the square root of any squared number is taken, it produces the actual number.

Let us discuss each of them to understand the concepts better.

Square Root by Long Division Method

The process of long division is one of the most common methods used to find the square roots of a given number. It is easy to comprehend and provides more reliable and accurate answers. The long division method reduces a multi-digit number to its equal parts.

Learning how to find the square root of a number is easy with the long division method. All you need are five primary operations- divide, multiply, subtract, bring down or raise, then repeat.

Following are the simple steps that must be followed to find the square root of 25 using the long division method:

Step 1

First, write the given number 25 in the division symbol, as shown in figure 1.

Step 2

Starting from the right side of the number, divide the number 25 into pairs such as 25 and 00.

Step 3

Now divide the digit 25 by a number, giving a number either 5 or less than 5. Therefore, in this case, the remainder is zero whereas the quotient is 5.

 

Step 4

The resulting quotient 5  is the square root of 25. Figure 1 given below shows the long division process in detail:

Important points

  • The number 25 is a perfect square.
  • The number 25 is a rational number.
  • The number 25 can be split into its prime factorization.

Is Square Root of 25 a Perfect Square?

The number  25 is a perfect square/ not a perfect square. A number is a perfect square if it splits into two equal parts or identical whole numbers. If a number is a perfect square, it is also rational.

A number expressed in p/q form is called a rational number. All the natural numbers are rational. A square root of a perfect square is a whole number; therefore, a perfect square is a rational number.

A number that is not a perfect square is irrational as it is a decimal number. As far as 25 is concerned, it is a perfect square. It can be proved as below:

Factorization of 25 results in 5 x 5 which can also be expressed as 5$^2$.

Taking the square root of the above expression gives:

= √(5$^2$)

= (5$^2$)$^{1/2}$

= 5

This shows that 25 is a perfect square and a rational number.

 

Therefore the above discussion proves that the square root of 25 is equivalent to 5.
