If a number is multiplied by itself, the result is a square. The inverse of the square is a square root. The square root is used in fields such as vehicle design and finance. Here, we will discuss the square root of 2705.

What is the Square Root of 2705?

The square root is the inverse of the square of the number. 2705 is not a perfect square. The square root of 2705 is expressed in both radical and exponential form. In the radical form, it is expressed as √2705, whereas in the exponential form it is expressed as (2705)^(1/2). √2705 ≈ 52.00769, 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 2705

The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where 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 2705 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 2705 is broken down into its prime factors.

Step 1: Finding the prime factors of 2705 Breaking it down, we get 5 x 541. Since 541 is a prime number, we stop here.

Step 2: Now we found out the prime factors of 2705. Since 2705 is not a perfect square, calculating 2705 using prime factorization is not straightforward.

Square Root of 2705 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 2705, we need to group it as 27 and 05.

Step 2: Now we need to find n such that n^2 is the largest perfect square less than or equal to 27. Here, n is 5 because 5^2 = 25 ≤ 27. The quotient is 5, and after subtracting 25 from 27, the remainder is 2.

Step 3: Bring down 05 to make it 205. Add the old divisor to itself (5 + 5) to get 10 as the new divisor.

Step 4: Find a digit x such that 10x * x ≤ 205. Here, x is 2 because 102 * 2 = 204.

Step 5: Subtract 204 from 205, leaving a remainder of 1. Since we want more precision, add a decimal point and bring down 00 to make it 100.

Step 6: The new divisor is 104 (102 + 2), and we find x such that 104x * x ≤ 100. Continue this process until the desired precision is achieved.

Square Root of 2705 by Approximation Method

The approximation method is another way to find square roots. It's an easy method to find the square root of a given number. Let us learn how to find the square root of 2705 using the approximation method.

Step 1: Find the closest perfect squares around 2705. The smallest perfect square less than 2705 is 2601 (51^2) and the largest perfect square greater than 2705 is 2809 (53^2). √2705 falls between 51 and 53.

Step 2: Use linear approximation: (2705 - 2601) / (2809 - 2601) ≈ 0.52 Add this to the lower bound: 51 + 0.52 ≈ 51.52

The approximate square root of 2705 is 51.52.

Common Mistakes and How to Avoid Them in the Square Root of 2705

Students do make mistakes while finding the square root, such as forgetting about the negative square root or skipping steps in the long division method. Let's look at a few of these mistakes in detail.

Problem 1

Can you help Max find the area of a square box if its side length is given as √2705?

Okay, lets begin

The area of the square is approximately 7315.52 square units.

Explanation

The area of the square = side^2.

The side length is given as √2705.

Area of the square = side^2

= √2705 x √2705

≈ 52.00769 x 52.00769

≈ 7315.52.

Therefore, the area of the square box is approximately 7315.52 square units.

Problem 2

A square-shaped building measuring 2705 square feet is built; if each of the sides is √2705, what will be the square feet of half of the building?

Okay, lets begin

1352.5 square feet

Explanation

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

Dividing 2705 by 2 = 1352.5

So, half of the building measures 1352.5 square feet.

Problem 3

Calculate √2705 x 5.

Okay, lets begin

Approximately 260.04

Explanation

The first step is to find the square root of 2705, which is approximately 52.00769.

The second step is to multiply 52.00769 by 5.

52.00769 x 5 ≈ 260.04

Problem 4

What will be the square root of (2705 + 95)?

Okay, lets begin

The square root is 54.

Explanation

To find the square root, we need to find the sum of (2705 + 95).

2705 + 95 = 2800, and then √2800 ≈ 52.915, which rounds to approximately 54.

Therefore, the square root of (2705 + 95) is approximately 54.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √2705 units and the width ‘w’ is 38 units.

Okay, lets begin

The perimeter of the rectangle is approximately 180.02 units.

Explanation

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

Perimeter = 2 × (√2705 + 38)

≈ 2 × (52.00769 + 38)

≈ 2 × 90.00769

≈ 180.02 units.
