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 fields like vehicle design, finance, etc. Here, we will discuss the square root of 739.
The square root is the inverse of the square of a number. 739 is not a perfect square. The square root of 739 is expressed in both radical and exponential form. In radical form, it is expressed as √739, whereas (739)^(1/2) is the exponential form. √739 ≈ 27.18935, which is an irrational number because it cannot be expressed as p/q, where p and q are integers and q ≠ 0.
The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, methods like long division and approximation are used. Let us now learn the following methods:
The product of prime factors is the prime factorization of a number. Now let us look at how 739 is broken down into its prime factors:
Step 1: Finding the prime factors of 739. 739 is a prime number itself, so its only factors are 1 and 739. Since 739 is not a perfect square, calculating √739 using prime factorization in pairs is not feasible.
The long division method is particularly useful 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, group the numbers from right to left. For 739, group it as 39 and 7.
Step 2: Now find n whose square is ≤ 7. We can say n is ‘2’ because 2 × 2 = 4, which is ≤ 7. The quotient is 2, and after subtracting 4 from 7, the remainder is 3.
Step 3: Bring down 39, making the new dividend 339. Add the old divisor with the same number, 2 + 2 = 4, to get a new divisor.
Step 4: Now find the largest n such that 4n × n ≤ 339. Let’s consider n as 8. Now, 48 × 8 = 384, which is greater than 339. Trying n as 7, we get 47 × 7 = 329, which is less than 339.
Step 5: Subtract 329 from 339, the difference is 10, and the quotient is 27.
Step 6: Since the dividend is less than the divisor, we add a decimal point and two zeroes to the dividend. The new dividend is 1000.
Step 7: Find the new divisor. The divisor is now 274, and we try n as 3, since 2743 × 3 = 8229. Continue these steps until we achieve the desired precision.
The square root of √739 is approximately 27.189.
The approximation method is another way to find square roots. It is an easy method to find the square root of a given number. Let's learn how to find the square root of 739 using the approximation method.
Step 1: Find the closest perfect squares of √739. The smallest perfect square below 739 is 729 (since √729 = 27), and the largest perfect square nearby is 784 (since √784 = 28). Thus, √739 falls between 27 and 28.
Step 2: Apply the formula: (Given number - smallest perfect square) ÷ (Greater perfect square - smallest perfect square). Using the formula, (739 - 729) ÷ (784 - 729) = 10 ÷ 55 ≈ 0.1818. Add the initial value to the decimal number: 27 + 0.1818 ≈ 27.1818. Thus, the square root of 739 is approximately 27.1818.
Students often make mistakes while finding square roots, such as forgetting about the negative square root, skipping long division steps, etc. Now let us look at a few of these mistakes in detail.
Can you help Max find the area of a square box if its side length is given as √739?
The area of the square is approximately 546.678 square units.
The area of the square = side².
The side length is given as √739.
Area of the square = side² = √739 × √739 ≈ 27.189 × 27.189 ≈ 739.
Therefore, the area of the square box is approximately 739 square units.
A square-shaped building measuring 739 square feet is built; if each side is √739, what will be the square feet of half of the building?
369.5 square feet
To find half the area, divide the given area by 2. 739 ÷ 2 = 369.5.
So, half of the building measures 369.5 square feet.
Calculate √739 × 5.
Approximately 135.945
First, find the square root of 739, which is approximately 27.189.
Then multiply 27.189 by 5.
So, 27.189 × 5 ≈ 135.945.
What will be the square root of (729 + 10)?
The square root is approximately 27.189.
To find the square root, first find the sum of (729 + 10). 729 + 10 = 739, and then find √739 ≈ 27.189.
Therefore, the square root of (729 + 10) is approximately ±27.189.
Find the perimeter of the rectangle if its length ‘l’ is √739 units and the width ‘w’ is 10 units.
The perimeter of the rectangle is approximately 74.378 units.
Perimeter of the rectangle = 2 × (length + width).
Perimeter = 2 × (√739 + 10) = 2 × (27.189 + 10) = 2 × 37.189 ≈ 74.378 units.
