Square Root of 12000

The square root is the inverse of the square of a number. 12000 is not a perfect square. The square root of 12000 can be expressed in both radical and exponential form. In radical form, it is expressed as √12000, whereas in exponential form, it is (12000)^(1/2). The approximate value of √12000 is 109.5445, 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, for non-perfect square numbers, the long division method and approximation method are used. Let us now learn about these methods:

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

The product of prime factors is the prime factorization of a number. Let's break down 12000 into its prime factors:

Step 1: Finding the prime factors of 12000 Breaking it down, we get 2 × 2 × 2 × 2 × 3 × 5 × 5 × 5 × 5: 2⁴ × 3¹ × 5⁴

Step 2: Now we have found the prime factors of 12000. The second step is to make pairs of those prime factors. Since 12000 is not a perfect square, the digits of the number can’t be grouped in perfect pairs.

Therefore, calculating 12000 using prime factorization does not give an exact square root.

The long division method is particularly useful for non-perfect square numbers. In this method, we determine 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: Group the numbers from right to left. In the case of 12000, we group it as 12 and 000.

Step 2: Find a number n such that n^2 is less than or equal to 12. The number is 3, because 3^2 = 9 is less than 12. Subtract 9 from 12 to get the remainder 3. Bring down the next pair of zeros to make it 300.

Step 3: Double the divisor (3) to get 6, and find a new digit n such that 6n × n is less than or equal to 300.

Step 4: The new quotient becomes 35, as 65 × 5 = 325 is less than 300. Subtract 300 from 325 to get the remainder 25. Bring down the next pair of zeros to make it 2500.

Step 5: Double the current quotient (35) to get 70, and find a new digit n such that 70n × n is less than or equal to 2500.

Step 6: The new quotient becomes 109.5. Continue this process until you have your desired decimal precision. The approximate square root of 12000 is 109.5445.

The approximation method is another way to find square roots and is a relatively easy method. Let us learn how to approximate the square root of 12000.

Step 1: Identify the closest perfect squares to 12000. The nearest perfect squares are 10816 (104²) and 12100 (110²). Therefore, √12000 falls between 104 and 110.

Step 2: Use the formula: (Given number - smaller perfect square) ÷ (Larger perfect square - smaller perfect square). (12000 - 10816) ÷ (12100 - 10816) = 1184 ÷ 1284 ≈ 0.922

Step 3: Add this decimal to the smaller perfect square's root: 104 + 0.922 ≈ 109.544

Therefore, the approximate square root of 12000 is 109.544.

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

• Approximation method: This method involves estimating the square root by finding two closest perfect squares and using interpolation.

• Long division method: A step-by-step division process used to find the square root of a non-perfect square.

• Perfect square: A number that is the square of an integer, such as 4, 9, 16, etc.
