Square Root of 1109

The square root is the inverse of the square of a number. 1109 is not a perfect square. The square root of 1109 is expressed in both radical and exponential form. In the radical form, it is expressed as √1109, whereas in the exponential form, it is expressed as (1109)^(1/2). √1109 ≈ 33.2947, 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 prime factorization method is not used; instead, the long division method and approximation method are utilized. 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 1109 is broken down into its prime factors:

Step 1: Finding the prime factors of 1109 Breaking it down, we get 1109 = 1 x 1109 (it is not easily broken into smaller prime factors since it is a semiprime).

Step 2: Since 1109 is not a perfect square and its prime factors don't form pairs, calculating 1109 using prime factorization is impractical.

The long division method is particularly used for non-perfect square numbers. In this method, we check the closest perfect square numbers 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 1109, we need to group it as 09 and 11.

Step 2: Find n whose square is less than or equal to 11. We can say n is 3 because 3 x 3 = 9, which is less than 11. Now the quotient is 3 and the remainder is 2 after subtracting 9 from 11.

Step 3: Bring down the next pair, 09, making the new dividend 209. Add the old divisor with the same number: 3 + 3 = 6, which will be our new divisor.

Step 4: The new divisor is 6n, and we need to find n such that 6n x n ≤ 209.

Step 5: Find n as 3, since 63 x 3 = 189. Step 6: Subtract 189 from 209, the difference is 20, and the quotient is 33.

Step 7: Add a decimal point and continue the process to get more decimal places.

Step 8: Continue doing these steps until we get two numbers after the decimal point or until the remainder is zero. So the square root of √1109 is approximately 33.29.

The approximation method is another method for finding square roots. It is an easy method to find the square root of a given number. Let us learn how to find the square root of 1109 using the approximation method.

Step 1: Find the closest perfect squares of √1109. The closest perfect squares are 1024 (32^2) and 1156 (34^2). √1109 falls between 32 and 34.

Step 2: Apply the formula (Given number - smaller perfect square) / (larger perfect square - smaller perfect square). Using the formula (1109 - 1024) / (1156 - 1024) = 85 / 132 ≈ 0.6439. Adding this to the smaller root, 32 + 0.6439 = 32.6439, so the square root of 1109 is approximately 33.29.

• 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, i.e., √16 = 4.

• Irrational Number: An irrational number is a number that cannot be written in the form 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, but the positive square root is most commonly used in real-world applications. It is known as the principal square root.

• Semiprime: A semiprime is a natural number that is the product of two prime numbers. For example, 1109 = 19 x 59.

• Decimal: If a number has a whole number and a fraction in a single number, then it is called a decimal. For example: 7.86, 8.65, and 9.42 are decimals.
