Detailed How-To: Understanding the Square Root of 150

To calculate the square root of 150, start by recognizing it as a product of its prime factors. Here’s a step-by-step process:

Step 1: Factorize 150

Break down 150 into its prime factors:

• 150 is divisible by 2 (since it’s even): 150 ÷ 2 = 75
• 75 is divisible by 3: 75 ÷ 3 = 25
• 25 is a square of 5: 25 ÷ 5 = 5
• Finally, 5 is a prime number.

So, 150 = 2 * 3 * 5 * 5.

Step 2: Simplify the square root

Now you can express 150 as a product of squares:

150 = 2 * 3 * (5 * 5) = 2 * 3 * 25

Recognize that 25 is a perfect square:

√150 = √(2 * 3 * 25)

Use the property of square roots that states √(a * b) = √a * √b:

√150 = √2 * √3 * √25

Since √25 = 5:

√150 = √2 * √3 * 5

This expression can't be simplified further in terms of elementary operations.

Step 3: Final Calculation

Approximate √2 * √3 for a more practical result:

Using a calculator, √2 ≈ 1.414 and √3 ≈ 1.732:

√2 * √3 ≈ 1.414 * 1.732 ≈ 2.449

Thus, √150 ≈ 2.449 * 5 ≈ 12.247.

So, the square root of 150 is approximately 12.247.

Let’s go over this process again with another practical example.

Detailed How-To: General Method for Finding Square Roots

Whether you are faced with finding the square root of any number, these steps will provide a robust method:

Step 1: Factorize the Number

Begin by factorizing the number into its prime factors. For example, for the number 288:

• 288 is divisible by 2: 288 ÷ 2 = 144
• 144 is divisible by 2: 144 ÷ 2 = 72
• 72 is divisible by 2: 72 ÷ 2 = 36
• 36 is divisible by 2: 36 ÷ 2 = 18
• 18 is divisible by 2: 18 ÷ 2 = 9
• 9 is divisible by 3: 9 ÷ 3 = 3
• 3 is divisible by 3: 3 ÷ 3 = 1

Thus, 288 = 2^5 * 3^2.

Step 2: Express as Perfect Squares

Rewrite the number in terms of its perfect squares:

288 = 144 * 2 = 144 * (2 * 1)

Notice that 144 is a perfect square: √144 = 12:

√288 = √(144 * 2) = 12 * √2

Without further simplification in elementary form, it’s good to estimate the value:

Calculate √2 using a calculator, which is approximately 1.414:

12 * 1.414 ≈ 16.968

So, √288 ≈ 16.968.

Step 3: Final Approximation

For a more precise result:

Combine the known values for the non-perfect square parts:

Thus, the square root of 288 is approximately 16.968.
