The prime factorization method is a systematic approach to finding the square root of a number by breaking it down into its prime factors. Here, we will find the square root of 22500 using this method.

1. Step 1: Factorize 22500 into its prime factors. Begin by dividing by the smallest prime numbers:
   • 22500 is even, so divide by 2: \[ 22500 \div 2 = 11250 \]
   • 11250 is even, so divide by 2 again: \[ 11250 \div 2 = 5625 \]
   • 5625 ends in 5, so divide by 5: \[ 5625 \div 5 = 1125 \]
   • 1125 ends in 5, so divide by 5: \[ 1125 \div 5 = 225 \]
   • 225 ends in 5, so divide by 5: \[ 225 \div 5 = 45 \]
   • 45 ends in 5, so divide by 5: \[ 45 \div 5 = 9 \]
   • 9 is divisible by 3: \[ 9 \div 3 = 3 \]
   • 3 is a prime number: \[ 3 \div 3 = 1 \]
2. Step 2: Write down all the prime factors: \[ 22500 = 2^2 \times 3^2 \times 5^4 \]
3. Step 3: Group the prime factors into pairs of equal factors: \[ (2 \times 2) \times (3 \times 3) \times (5^2 \times 5^2) \]
4. Step 4: Take one factor from each pair and multiply them together: \[ 2 \times 3 \times 25 = 2 \times 3 \times (5 \times 5) = 2 \times 3 \times 25 = 150 \]
5. Result: The square root of 22500 is: \[ \sqrt{22500} = 150 \]

Using the prime factorization method ensures that we find the square root accurately by breaking down the number into its basic building blocks and methodically reconstructing the root.

The long division method is a manual technique to find the square root of a number, which involves a step-by-step approach similar to traditional long division. Here’s how you can find the square root of 22500 using this method:

1. Pair the Digits: Starting from the decimal point (or from the right if it’s a whole number), pair the digits in groups of two. For 22500, we have pairs (22)(50)(00).

2. Find the Largest Square: Determine the largest number whose square is less than or equal to the first pair (22). The largest number is 4, since \(4^2 = 16\) and \(5^2 = 25\) is too large. Write 4 above the line and 16 below 22, then subtract:

   \(22 - 16 = 6\)

3. Bring Down the Next Pair: Bring down the next pair of digits (50), making the new number 650.

4. Double the Quotient: Double the current quotient (4), which gives 8, and write it as a partial divisor (80_).

5. Find the Next Digit: Find a digit (X) such that \(80X \times X \leq 650\). The digit is 7 because \(807 \times 7 = 5649\). Write 7 in the quotient and 49 below 650, then subtract:

   \(650 - 567 = 83\)

6. Bring Down the Next Pair: Bring down the next pair of digits (00), making the new number 8300.

7. Double the Quotient: Double the current quotient (47), which gives 94, and write it as a partial divisor (940_).

8. Find the Next Digit: Find a digit (Y) such that \(940Y \times Y \leq 8300\). The digit is 8 because \(9408 \times 8 = 75264\). Write 8 in the quotient and 64 below 8300, then subtract:

   \(8300 - 75264 = 936\)

9. Continue the Process: Continue the process until the desired accuracy is achieved. Since the pairs are exhausted, the quotient obtained is the square root of 22500.

Thus, the square root of 22500 using the long division method is approximately 150.
