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 10.29.

What is the Square Root of 10.29?

The square root is the inverse of the square of the number. 10.29 is not a perfect square. The square root of 10.29 is expressed in both radical and exponential form. In the radical form, it is expressed as √10.29, whereas (10.29)^(1/2) in the exponential form. √10.29 ≈ 3.207, 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 10.29

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 10.29 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. However, since 10.29 is not a perfect square, calculating its square root using prime factorization is not feasible.

Square Root of 10.29 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 group the numbers from right to left. In the case of 10.29, we consider it as 10 and 29.

Step 2: Now we need to find a number n whose square is less than or equal to 10. We can say n is 3 because 3 × 3 = 9, which is less than 10. Subtracting gives a remainder of 1.

Step 3: Bring down 29, making the new dividend 129. Add the old divisor (3) with itself, resulting in 6 as the new divisor.

Step 4: Find the largest digit x such that 6x × x ≤ 129. We find that x is 2 because 62 × 2 = 124, which is less than 129. Subtract to get a remainder of 5.

Step 5: Since the dividend is less than the divisor, we need to add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend, making it 500.

Step 6: The new divisor becomes 64, and we determine the next digit of the quotient.

Repeating similar steps, we get an approximate value for the square root of 10.29 as 3.207.

Square Root of 10.29 by Approximation Method

The approximation method is another method for finding the square roots. It is an easy method to find the square root of a given number. Let us learn how to find the square root of 10.29 using the approximation method.

Step 1: Now we have to find the closest perfect squares surrounding 10.29. The smallest perfect square less than 10.29 is 9, and the largest perfect square greater than 10.29 is 16. So, √10.29 falls somewhere between 3 and 4.

Step 2: Now we apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) (10.29 - 9) / (16 - 9) = 1.29 / 7 ≈ 0.1843 Using the formula, we identified the decimal point of our square root.

Adding the integer part, we get 3 + 0.1843 = 3.1843, so the approximate square root of 10.29 is about 3.207.

Common Mistakes and How to Avoid Them in the Square Root of 10.29

Students do make mistakes while finding the square root, like forgetting about the negative square root and skipping steps in the long division method. 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 √10?

Okay, lets begin

The area of the square is 10 square units.

Explanation

The area of the square = side^2.

The side length is given as √10.

Area of the square = side^2 = √10 × √10 = 10.

Therefore, the area of the square box is 10 square units.

Problem 2

A square-shaped building measuring 10.29 square feet is built; if each of the sides is √10.29, what will be the square feet of half of the building?

Okay, lets begin

5.145 square feet

Explanation

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

Dividing 10.29 by 2 gives 5.145.

So half of the building measures 5.145 square feet.

Problem 3

Calculate √10.29 × 2.

Okay, lets begin

6.414

Explanation

The first step is to find the square root of 10.29, which is approximately 3.207.

The second step is to multiply 3.207 by 2.

So, 3.207 × 2 ≈ 6.414.

Problem 4

What will be the square root of (10 + 2)?

Okay, lets begin

The square root is approximately 3.464.

Explanation

To find the square root, we need to find the sum of (10 + 2). 10 + 2 = 12, and the square root of 12 is approximately 3.464.

Therefore, the square root of (10 + 2) is ±3.464.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √10 units and the width ‘w’ is 5 units.

Okay, lets begin

The perimeter of the rectangle is approximately 20.324 units.

Explanation

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

Perimeter = 2 × (√10 + 5) = 2 × (3.162 + 5) = 2 × 8.162 ≈ 20.324 units.
