There are several methods to calculate the square root of 10000. Below are the most commonly used methods with detailed steps:

Prime Factorization Method

1. Start with the number 10000.
2. Find the prime factors of 10000:
   • 10000 ÷ 2 = 5000
   • 5000 ÷ 2 = 2500
   • 2500 ÷ 2 = 1250
   • 1250 ÷ 2 = 625
   • 625 ÷ 5 = 125
   • 125 ÷ 5 = 25
   • 25 ÷ 5 = 5
   • 5 ÷ 5 = 1
3. Express 10000 as the product of its prime factors:

   10000 = 2⁴ × 5⁴

4. Take the square root of each factor:

   √10000 = √(2⁴ × 5⁴) = 2² × 5² = 4 × 25 = 100

Long Division Method

1. Pair the digits of 10000 from right to left (100 00).
2. Find the largest number whose square is less than or equal to the first pair (100):
   • 10 × 10 = 100
3. Write 10 as the first digit of the root.
4. Subtract the product from the first pair and bring down the next pair:
   • 100 - 100 = 0, bring down 00 → 00
5. The next divisor is double the quotient obtained (2 × 10 = 20). Find a digit X such that (20X × X) is less than or equal to 00:
   • Since 00 is less than 20, the next digit is 0.
6. Continue the process until all pairs are used. The quotient obtained is 100.

Repeated Subtraction Method

1. Start with the number 10000.
2. Subtract consecutive odd numbers starting from 1, and count the steps until you reach zero:
   • 10000 - 1 = 9999
   • 9999 - 3 = 9996
   • 9996 - 5 = 9991
   • ...
   • 4th subtraction: 9991 - 7 = 9984
   • Continue subtracting until the count of subtractions is 100.
3. The number of subtractions required to reach zero is the square root. Here, it takes 100 subtractions to reach zero, so √10000 = 100.

The square root of 10000, which is 100, has numerous applications in various fields of mathematics and real-life scenarios. Here are some detailed examples and applications:

• Solving Quadratic Equations

Quadratic equations often involve finding the square roots of numbers. For example, consider the equation \(x^2 - 10000 = 0\). To solve for \(x\), we add 10000 to both sides to get \(x^2 = 10000\), and then take the square root of both sides, resulting in \(x = \pm 100\).

• Calculating Areas and Perimeters

In geometry, the area and perimeter of squares are frequently calculated using square roots. For instance, if a square plot has an area of 10000 square meters, its side length \(a\) can be found using \(a = \sqrt{10000} = 100\) meters. Consequently, the perimeter \(P\) of the plot is \(P = 4 \times 100 = 400\) meters.

• Practical Applications in Geometry

Square roots are essential in various geometric calculations. For example, in architecture and construction, determining the diagonal length of a square plot or the dimensions required for a particular area often involves calculating square roots.

• Example Calculations
1. Finding the smallest number to make a perfect square: To make 9985 a perfect square, we need to add 15 (since \(10000 - 9985 = 15\)). Thus, \(9985 + 15 = 10000\) and the square root is \(\sqrt{10000} = 100\).
2. Determining a multiplier for a perfect square: To make 1000 a perfect square, multiply by 10 (since \(1000 \times 10 = 10000\)). Therefore, \(\sqrt{10000} = 100\).
