If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in the field of vehicle design, finance, etc. Here, we will discuss the square root of 46.1

What is the Square Root of 46.1?

The square root is the inverse of the square of the number. 46.1 is not a perfect square. The square root of 46.1 is expressed in both radical and exponential form.

In the radical form, it is expressed as √46.1, whereas (46.1)^(1/2) in the exponential form. √46.1 ≈ 6.791, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 46.1

The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where the long-division method and approximation method are used. Let us now learn the following methods:

  • Prime factorization method
  • Long division method
  • Approximation method

Square Root of 46.1 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Since 46.1 is not a perfect square, using prime factorization directly is not feasible. Therefore, calculating the square root of 46.1 using prime factorization is not possible.

Square Root of 46.1 by Long Division Method

The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.

Step 1: To begin with, we need to pair up the digits from right to left. In the case of 46.1, we consider 46 and 10.

Step 2: Now we need to find n whose square is closest to 46. We can say n is 6 because 6 × 6 = 36, which is less than 46. Now the quotient is 6, and after subtracting 36 from 46, the remainder is 10.

Step 3: Now let us bring down 10, making the new dividend 1010. Add the old divisor with the same number: 6 + 6 = 12, making it our new divisor.

Step 4: The new divisor, 12n, is adjusted to find n such that 12n × n ≤ 1010. Let us consider n as 8, as 128 × 8 = 1024, which exceeds 1010. So, n should be 7, making 127 × 7 = 889.

Step 5: Subtract 889 from 1010; the difference is 121.

Step 6: Since the remainder exists, we need to add a decimal point and continue the process by bringing down pairs of zeros.

Step 7: Continue this process until you have two decimal places of accuracy.

The square root of 46.1 is approximately 6.791.

Square Root of 46.1 by Approximation Method

The approximation method is another method for finding square roots. It is an easy method to find the square root of a given number. Now let us learn how to find the square root of 46.1 using the approximation method.

Step 1: Now we have to find the closest perfect square of √46.1. The smallest perfect square below 46.1 is 36 (6^2) and the largest perfect square above 46.1 is 49 (7^2). Therefore, √46.1 is between 6 and 7.

Step 2: Now we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square).

Using the formula: (46.1 - 36) / (49 - 36) = 10.1 / 13 = 0.7769 Adding this to the lower bound, we get 6 + 0.7769 ≈ 6.777.

Therefore, the square root of 46.1 is approximately 6.791 after further refinement.

Common Mistakes and How to Avoid Them in the Square Root of 46.1

Students do make mistakes while finding the square root, such as forgetting about the negative square root, skipping long division methods, etc. Now let us look at a few of those mistakes that students tend to make in detail.

Problem 1

Can you help Max find the area of a square box if its side length is given as √46.1?

Okay, lets begin

The area of the square is approximately 46.1 square units.

Explanation

The area of the square = side^2.

The side length is given as √46.1.

Area of the square = side^2 = √46.1 × √46.1 = 46.1.

Therefore, the area of the square box is approximately 46.1 square units.

Problem 2

A square-shaped building measuring 46.1 square feet is built; if each of the sides is √46.1, what will be the square feet of half of the building?

Okay, lets begin

23.05 square feet

Explanation

We can just divide the given area by 2 as the building is square-shaped.

Dividing 46.1 by 2 gives us 23.05.

So half of the building measures 23.05 square feet.

Problem 3

Calculate √46.1 × 5.

Okay, lets begin

Approximately 33.955

Explanation

The first step is to find the square root of 46.1, which is approximately 6.791.

The second step is to multiply 6.791 by 5. So, 6.791 × 5 ≈ 33.955.

Problem 4

What will be the square root of (36 + 10.1)?

Okay, lets begin

The square root is approximately 6.791.

Explanation

To find the square root, we need to find the sum of (36 + 10.1). 36 + 10.1 = 46.1, and then √46.1 ≈ 6.791.

Therefore, the square root of (36 + 10.1) is approximately ±6.791.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √46.1 units and the width ‘w’ is 38 units.

Okay, lets begin

We find the perimeter of the rectangle is approximately 89.582 units.

Explanation

Perimeter of the rectangle = 2 × (length + width).

Perimeter = 2 × (√46.1 + 38) = 2 × (6.791 + 38) = 2 × 44.791 ≈ 89.582 units.
