Calculating the square root of 1500 involves various methods, each with its unique approach and accuracy. Here, we explore some of the most common methods for finding the square root.

1. Prime Factorization Method

The prime factorization method involves breaking down 1500 into its prime factors and then pairing them.

• Step 1: Write the prime factorization of 1500: \(1500 = 2^2 \times 3 \times 5^3\)
• Step 2: Pair the prime factors: \((2 \times 2) \times 3 \times (5 \times 5) \times 5\)
• Step 3: Take one factor from each pair and multiply: \(2 \times 5 = 10\)
• Step 4: The square root is approximately: \(10 \sqrt{3 \times 5} = 10 \sqrt{15}\)

2. Long Division Method

The long division method is a systematic way to find the square root by dividing and averaging. This method is particularly useful for larger numbers.

1. Step 1: Pair the digits of 1500 from right to left: 15 | 00
2. Step 2: Find the largest number whose square is less than or equal to 15: \(3^2 = 9\)
3. Step 3: Subtract and bring down the next pair: \(15 - 9 = 6\), bring down 00 to get 600
4. Step 4: Double the quotient (3) to get 6 and find a new digit: \(61 \times 1 = 61\)
5. Step 5: Subtract and bring down the next pair, repeat until the desired precision is achieved.

3. Babylonian Method (Heron's Method)

The Babylonian method is an ancient iterative method for approximating square roots. It starts with an initial guess and refines it repeatedly.

• Step 1: Choose an initial guess \(x_0\). A good starting point for 1500 might be 40.
• Step 2: Apply the iteration formula: \(x_{n+1} = \frac{x_n + \frac{1500}{x_n}}{2}\)
• Step 3: Repeat the iteration until the difference between \(x_n\) and \(x_{n+1}\) is less than a desired tolerance level.
• Step 4: The value of \(x_n\) converges to \(\sqrt{1500}\).

4. Calculator Method

Using a calculator is the simplest and fastest method to find the square root of 1500.

• Step 1: Enter 1500 into the calculator.
• Step 2: Press the square root function key (\(\sqrt{\ }\)).
• Step 3: Read the result, which is approximately 38.7298.

Conclusion

Each method provides a different approach to finding the square root of 1500. While the prime factorization and Babylonian methods offer insightful manual calculations, the long division method provides systematic steps, and using a calculator offers quick precision.
