Square Root of 10100

The square root is the inverse of squaring a number. 10100 is not a perfect square. The square root of 10100 can be expressed in both radical and exponential forms. In radical form, it is expressed as √10100, whereas in exponential form it is (10100)^(1/2). √10100 ≈ 100.49875, which is an irrational number because it cannot be expressed as a fraction p/q, where p and q are integers and q ≠ 0.

The prime factorization method is typically used for perfect squares. However, for non-perfect squares like 10100, the long-division method and approximation methods are more suitable. Let us now explore these methods:

• Prime factorization method
• Long division method
• Approximation method

Prime factorization involves expressing a number as a product of prime factors. Let's see how 10100 is broken down:

Step 1: Finding the prime factors of 10100

Breaking it down, we get 2 x 2 x 5 x 5 x 101: 2^2 x 5^2 x 101

Step 2: Since 10100 is not a perfect square, the digits cannot be grouped into pairs completely. Therefore, calculating √10100 using prime factorization is not straightforward.

The long division method is useful for non-perfect squares. Here's how to find the square root using this method, step by step:

Step 1: Group the digits of 10100 from right to left as 00, 10, and 1.

Step 2: Find n whose square is less than or equal to 1. Here, n is 1 because 1 x 1 = 1. The quotient is 1, and after subtracting, the remainder is 0.

Step 3: Bring down 10, making the new dividend 10. Add the old divisor with itself to get 2, which is the new divisor.

Step 4: Find n such that 2n x n ≤ 10. Here, n is 4, since 2 x 4 x 4 = 8.

Step 5: Subtract 8 from 10 to get 2, and the quotient becomes 14.

Step 6: Bring down the next pair, 00, to make the dividend 200.

Step 7: Find n such that 28n x n ≤ 200. Here, n is 7, since 287 x 7 = 2009, but we should adjust to get 196 as 28 x 7 x 7 = 196.

Step 8: Subtract 196 from 200 to get 4, and the quotient becomes 100.

Step 9: Since the dividend is less than the divisor, add a decimal point and bring down more zeros. Continue this process to get a more precise result.

The square root of 10100 is approximately 100.49875.

The approximation method is a simple way to estimate square roots. Let's find the square root of 10100 using approximation:

Step 1: Identify the closest perfect squares around 10100. The closest are 10000 (100^2) and 10201 (101^2). √10100 lies between 100 and 101.

Step 2: Apply the formula: (Given number - smaller perfect square) / (Larger perfect square - smaller perfect square) (10100 - 10000) ÷ (10201 - 10000) = 100 / 201 ≈ 0.497512

Step 3: Add this decimal to the smaller perfect square's root: 100 + 0.497512 ≈ 100.49875 Therefore, the square root of 10100 is approximately 100.49875.

• Square root: A square root is the inverse of squaring a number. Example: 4^2 = 16, and the inverse operation is √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: Although numbers have both positive and negative square roots, the positive square root is typically used in practical applications, known as the principal square root.
   
• Radical form: A number expressed with a radical symbol. For example, √10100 is in radical form.
   
• Exponential form: A number expressed with an exponent, such as (10100)^(1/2), representing the square root.
