Square Root of 1370

The square root is the inverse of the square of the number. 1370 is not a perfect square. The square root of 1370 is expressed in both radical and exponential forms. In the radical form, it is expressed as √1370, whereas (1370)^(1/2) in the exponential form. √1370 ≈ 37.0135, 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 1370 is broken down into its prime factors.

Step 1: Finding the prime factors of 1370

Breaking it down, we get 2 x 5 x 137: 2¹ x 5¹ x 137¹

Step 2: Now we found out the prime factors of 1370. The second step is to make pairs of those prime factors. Since 1370 is not a perfect square, the digits of the number can’t be grouped in pairs. Therefore, calculating 1370 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 1370, we need to group it as 70 and 13.

Step 2: Now we need to find n whose square is less than or equal to 13. We can say n as ‘3’ because 3 x 3 = 9 is less than 13. Now the quotient is 3, and after subtracting 9 from 13, the remainder is 4.

Step 3: Now let us bring down 70, which is the new dividend. Add the old divisor with the same number 3 + 3; we get 6, which will be our new divisor.

Step 4: The new divisor will be the sum of the divisor 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 x n ≤ 470. Let us consider n as 7, now 67 x 7 = 469.

Step 6: Subtract 469 from 470; the difference is 1, and the quotient is 37.

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 100.

Step 8: Now we need to find the new divisor that is 740 because 740 x 0 = 0.

Step 9: Subtracting 0 from 100, we get the result 100.

Step 10: Now the quotient is 37.0

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

So the square root of √1370 ≈ 37.01

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 1370 using the approximation method.

Step 1: Now we have to find the closest perfect square of √1370. The smallest perfect square less than 1370 is 1296, and the largest perfect square greater than 1370 is 1444. √1370 falls somewhere between 36 and 38.

Step 2: Now we need to apply the formula that is: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) Going by the formula (1370 - 1296) ÷ (1444 - 1296) ≈ 0.74 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 36 + 0.74 = 36.74.

So the approximate square root of 1370 is 36.74.

• 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 the principal square root.

• Long division method: A method used to find the square root of non-perfect squares by dividing and approximating the divisor and quotient.

• Approximation method: A method used to estimate the square root of a number by finding the closest perfect squares and interpolating between them.
