Square Root of 625 + Solution With Free Steps
Let us discuss the square root of the number 625 in detail and identify whether the number 625 is a perfect square number or not. This article provides the complete solution using different methods like long division etc. The square root of 625 can also be written as √625.
In this article, we will analyze and find the square root of 625 using various mathematical techniques, such as the approximation method and the long division method.
What Is the Square Root Of 625?
The square root of the number 625 is 25.
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:
√625 = √(25 x 25)
√625 = √(25)$^2$
√625 = ±25
The square can be canceled with the square root as it is equivalent to 1/2; therefore, obtaining 25. Hence 25 is 625’s square root. The square root generates both positive and negative integers.
How To Calculate the Square Root of 625?
You can calculate the square root of 625 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 625 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 625 using the long division method:
Step 1
First, write the given number 625 in the division symbol, as shown in figure 1.
Step 2
Starting from the right side of the number, divide the number 625 into pairs such as 25 and 6.
Step 3
Now divide the digit 6 by a number, giving a number either 6 or less than 6. Therefore, in this case, the remainder is 2, whereas the quotient is 2.
Step 4
After this, bring down the next pair 25. Now the dividend is bc. To find the next divisor, we need to double our quotient obtained before. Doubling 2 gives 4; hence consider it as the next divisor.
Step 5
Now pair 4 with another number to make a new divisor that results in $\leq$ 225 when multiplied with the divisor.
Step 6
Adding 5 to the divisor and multiplying 45 with 5 results in 225 $\eq$ 225. The remainder obtained is 0.
Step 7
The resulting quotient 25 is the square root of 625. Figure 1 given below shows the long division process in detail:

Square Root by Approximation Method
The approximation method involves guessing the square root of the non-perfect square number by dividing it by the perfect square lesser or greater than that number and taking the average.
The given detailed steps must be followed to find the square root of 625 using the approximation technique.
Step 1
Consider a perfect square number 576 less than 625.
Step 2
Now divide 625 by √576.
625 ÷ 24 = 26
Step 3
Now take the average of 24 and 26. The resulting number is approximately equivalent to the square root of 625.
(24 + 26) ÷ 2 = 25
Important points
- The number 625 is a perfect square.
- The number 625 is a rational number.
- The number 625 can be split into its prime factorization.
Is Square Root of 625 a Perfect Square?
The number X is 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 625 is concerned, it is a perfect square. It can be proved as below:
Factorization of 625 results in 25 x 25 which can also be expressed as 25$^2$.
Taking the square root of the above expression gives:
= √(25$^2$)
= (25$^2$)$^{1/2}$
= 25
This shows that 625 is a perfect square and a rational number.
Therefore the above discussion proves that the square root of 625 is equivalent to 25.
