Square Root of 4000 + Solution With Free Steps

Let us find out the square root of a four-digit number using different techniques. In this article, we discuss the 4000 number for which we are going to take the square root of this four-digit number which is equal to √4000=63.245.

In this article, we will analyze and find the square root of 4000 using various mathematical techniques, such as the approximation method and the long division method.

What Is the Square Root Of 4000?

The square root of the number 4000 is 63.245.

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:

√4000 = √(63.245 x 63.245)

√4000 = √(63.245)$^2$

√4000 = ±63.245

The square can be canceled with the square root as it is equivalent to 1/2; therefore, obtaining 63.245. Hence 63.245 is 4000’s square root. The square root generates both positive and negative integers.

How To Calculate the Square Root of 4000?

You can calculate the square root of 4000 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 4000 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 of 4000 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 4000 using the long division method:

Step 1

First, write the given number 4000 in the division symbol, as shown in figure 1.

Step 2

Starting from the right side of the number, divide the number 4000 into pairs such as 00 and 40.

Step 3

Now divide the digit 40 by a number, giving a number either 40 or less than 40. Therefore, in this case, the remainder is 4, whereas the quotient is 6.

Step 4

After this, bring down the next pair 00. Now the dividend is 400. To find the next divisor, we need to double our quotient obtained before. Doubling 6 gives 12; hence consider it as the next divisor.

Step 5

Now pair 12 with another number to make a new divisor that results in $\leq$ 400 when multiplied with the divisor.

Step 6

Adding 3 to the divisor and multiplying 123 with 3 results in 369 $\leq$ 400. The remainder obtained is 31. Move the next pair of zeros down and repeat the same process mentioned above.

Step 7

Keep on repeating the same steps till the zero remainder is obtained or if the division process continues infinitely, solve to two decimal places.

Step 8

The resulting quotient 63.245 is the square root of 4000. 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 4000 using the approximation technique.

Step 1

Consider a perfect square number 3969 less than 4000.

Step 2

Now divide 4000 by √3969.

4000 ÷ 63 = 63.49

Step 3

Now take the average of 63 and 63.49. The resulting number is approximately equivalent to the square root of 4000.

(63 + 63.49) ÷ 2 = 63.24

Important points

  • The number 4000 is not a perfect square.
  • The number 4000 is a rational number.
  • The number 4000 can be split into its prime factorization.

Is Square Root of 4000 a Perfect Square?

The number 4000 is 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 4000 is concerned, it is not a perfect square. It can be proved as below:

Factorization of 4000 results in 10 x 400.

Taking the square root of the above expression gives:

= √(10 x 400)

= (10 x 400)$^{1/2}$

= 63.245

This shows that 4000 is not a perfect square as it has decimal places; hence it is an irrational number.

Therefore the above discussion proves that the square root of 4000 is equivalent to 63.245.Square Root Of 4000
