Square Root of 1274

The square root is the inverse of the square of the number. 1274 is not a perfect square. The square root of 1274 is expressed in both radical and exponential form. In the radical form, it is expressed as √1274, whereas (1274)^(1/2) in the exponential form. √1274 ≈ 35.698, 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:

• Prime factorization method
• Long division method
• Approximation method

The product of prime factors is the prime factorization of a number. Now let us look at how 1274 is broken down into its prime factors.

Step 1: Finding the prime factors of 1274 Breaking it down, we get 2 x 7 x 7 x 13: 2^1 x 7^2 x 13^1

Step 2: Now we found out the prime factors of 1274. The second step is to make pairs of those prime factors. Since 1274 is not a perfect square, therefore the digits of the number can’t be grouped in pairs.

Therefore, calculating 1274 using prime factorization is not straightforward.

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 1274, we need to group it as 74 and 12.

Step 2: Now we need to find n whose square is less than or equal to 12. We can say n is ‘3’ because 3 x 3 = 9, which is less than 12. The quotient is 3, and after subtracting 9 from 12, the remainder is 3.

Step 3: Now, let us bring down 74, which is the new dividend. Add the old divisor with the quotient, 3 + 3, to get 6, which will be our new divisor.

Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 6n as the new divisor; we need to find the value of n.

Step 5: The next step is finding 6n × n ≤ 374. Let us consider n as 6, now 66 x 6 = 396, which is too large, so n must be 5.

Step 6: Subtract 330 from 374, the difference is 44, and the quotient is 35.

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. The new dividend is 4400.

Step 8: Now we need to find a new divisor. Trying n as 7, we find 707 x 7 = 4949, which is too large, so n must be 6.

Step 9: Subtracting 4236 from 4400, we get the result 164.

Step 10: Now the quotient is 35.6

Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there is no decimal values continue till the remainder is zero.

So the square root of √1274 ≈ 35.698

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 1274 using the approximation method.

Step 1: Now we have to find the closest perfect squares of √1274. The smallest perfect square less than 1274 is 1225, and the largest perfect square greater than 1274 is 1369. √1274 falls somewhere between 35 and 37.

Step 2: Now we need to apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Going by the formula (1274 - 1225) / (1369 - 1225) ≈ 0.48 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 35 + 0.48 = 35.48.

So the approximate square root of 1274 is 35.48.

• Square root: A square root is the inverse of a square. Example: 4^2 = 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, 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 the principal square root.
   
• Prime factorization: Breaking down a number into its prime factors. For example, the prime factorization of 18 is 2 × 3 × 3.
   
• Long division method: A technique used to find the square root of a non-perfect square by using division.
