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 716.
The square root is the inverse of the square of the number. 716 is not a perfect square. The square root of 716 is expressed in both radical and exponential form. In the radical form, it is expressed as √716, whereas (716)^(1/2) in the exponential form. √716 ≈ 26.743, 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.
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:
The product of prime factors is the prime factorization of a number. Now let us look at how 716 is broken down into its prime factors.
Step 1: Finding the prime factors of 716
Breaking it down, we get 2 × 2 × 179: 2^2 × 179
Step 2: Now we found out the prime factors of 716. The second step is to make pairs of those prime factors. Since 716 is not a perfect square, therefore the digits of the number can’t be grouped in pairs. Therefore, calculating 716 using prime factorization is not possible.
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 716, we need to group it as 16 and 7.
Step 2: Now we need to find n whose square is 7. We can say n as ‘2’ because 2 × 2 = 4, which is lesser than 7. Now the quotient is 2, and after subtracting 4 from 7, the remainder is 3.
Step 3: Now let us bring down 16, which is the new dividend. Add the old divisor with the same number 2 + 2 to get 4, which will be our new divisor.
Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 4n as the new divisor, we need to find the value of n.
Step 5: The next step is finding 4n × n ≤ 316. Let us consider n as 7, now 47 × 7 = 329, which is too large.
Step 6: Try with n as 6, now 46 × 6 = 276.
Step 7: Subtract 276 from 316, the difference is 40, and the quotient is 26.
Step 8: 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. Now the new dividend is 4000.
Step 9: Now we need to find the new divisor that is 534 because 534 × 7 = 3738.
Step 10: Subtracting 3738 from 4000, we get the result 262.
Step 11: Now the quotient is 26.7
Step 12: Continue doing these steps until we get two numbers after the decimal point. Suppose if there are no decimal values, continue till the remainder is zero.
So the square root of √716 is approximately 26.74.
The approximation method is another method for finding the square roots, and 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 716 using the approximation method.
Step 1: Now we have to find the closest perfect square of √716. The smallest perfect square less than 716 is 676 (26^2), and the largest perfect square greater than 716 is 729 (27^2). √716 falls somewhere between 26 and 27.
Step 2: Now we need to apply the formula (Given number - smaller perfect square) ÷ (larger perfect square - smaller perfect square). Applying the formula: (716 - 676) ÷ (729 - 676) = 40 ÷ 53 ≈ 0.7547 Using the formula, we identified the decimal point of our square root. The next step is adding the value we got initially to the decimal number, which is 26 + 0.7547 = 26.7547, so the square root of 716 is approximately 26.75.
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.
Can you help Max find the area of a square box if its side length is given as √716?
The area of the square is 716 square units.
The area of the square = side^2.
The side length is given as √716.
Area of the square = side^2 = √716 × √716 = 716.
Therefore, the area of the square box is 716 square units.
A square-shaped garden measuring 716 square feet is built; if each of the sides is √716, what will be the square feet of half of the garden?
358 square feet
We can just divide the given area by 2 as the garden is square-shaped.
Dividing 716 by 2, we get 358.
So half of the garden measures 358 square feet.
Calculate √716 × 5.
133.715
The first step is to find the square root of 716, which is approximately 26.743, the second step is to multiply 26.743 with 5. So 26.743 × 5 = 133.715.
What will be the square root of (700 + 16)?
The square root is approximately 26.743
To find the square root, we need to find the sum of (700 + 16). 700 + 16 = 716, and then √716 ≈ 26.743. Therefore, the square root of (700 + 16) is ±26.743.
Find the perimeter of the rectangle if its length ‘l’ is √716 units and the width ‘w’ is 38 units.
The perimeter of the rectangle is approximately 129.486 units.
Perimeter of the rectangle = 2 × (length + width)
Perimeter = 2 × (√716 + 38) = 2 × (26.743 + 38) = 2 × 64.743 = 129.486 units.
