Square Root of 528

The square root is the inverse of the square of the number. 528 is not a perfect square. The square root of 528 is expressed in both radical and exponential form. In the radical form, it is expressed as √528, whereas (528)^(1/2) in the exponential form. √528 ≈ 22.97825, 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 the long-division method and approximation method are used. Let us now learn the following methods:

1. Prime factorization method
2. Long division method
3. Approximation method

The product of prime factors is the prime factorization of a number. Now let us look at how 528 is broken down into its prime factors.

Step 1: Finding the prime factors of 528 Breaking it down, we get 2 x 2 x 2 x 2 x 3 x 11: 2⁴ x 3¹ x 11¹

Step 2: Now we found the prime factors of 528. The second step is to make pairs of those prime factors. Since 528 is not a perfect square, the digits of the number can’t be grouped in pairs.

Therefore, calculating 528 using prime factorization is impossible.

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 528, we need to group it as 28 and 5.

Step 2: Now we need to find n whose square is 5. We can say n as ‘2’ because 2 x 2 ≤ 5. Now the quotient is 2, after subtracting 5 - 4, the remainder is 1.

Step 3: Now let us bring down 28, which is the new dividend. Add the old divisor with the same number: 2 + 2 = 4, which will be our new divisor.

Step 4: The new divisor will be the sum of the old divisor and the quotient. Now we get 4n as the new divisor, and we need to find the value of n.

Step 5: The next step is finding 4n × n ≤ 128. Let us consider n as 2, now 4 x 2 x 2 = 88.

Step 6: Subtract 128 from 88, the difference is 40, and the quotient is 22.

Step 7: 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 8: Now we need to find the new divisor, which is 229 because 229 x 9 = 2061.

Step 9: Subtracting 2061 from 4000, we get the result 1939.

Step 10: Now the quotient is 22.9.

Step 11: 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 √528 is approximately 22.98.

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 528 using the approximation method.

Step 1: Now we have to find the closest perfect square of √528. The smallest perfect square less than 528 is 484 (22²), and the largest perfect square greater than 528 is 529 (23²). √528 falls somewhere between 22 and 23.

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

Going by the formula: (528 - 484) ÷ (529 - 484) = 44 ÷ 45 ≈ 0.98 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 22 + 0.98 = 22.98, so the square root of 528 is approximately 22.98.

• Square root: A square root is the inverse of a square. Example: 4² = 16, and the inverse of the square is the square root, that is, √16 = 4.

• Irrational number: An irrational number is a number that cannot be written in the form of p/q, where q is not equal to zero, and p and q are integers.

• Principal square root: A number has both positive and negative square roots; however, it is always the positive square root that has more prominence due to its uses in the real world. That is the reason it is also known as a principal square root.

• Approximation: An approximation is a value or number that is close to, but not exactly, the exact number or value.

• Prime factorization: Prime factorization is the process of expressing a number as the product of its prime factors.
