Formula Explained

The formula for multiplying square roots is based on the property of square roots that states:

This means you can multiply two square roots by first multiplying the numbers under the square roots and then taking the square root of the product.

For example, if you have √(4) × √(9), you can calculate it as follows:

This property is fundamental in simplifying square root expressions and solving problems in various fields.

Worked Examples

Example 1: Simple Multiplication

Let's calculate √(16) × √(25):

1. First, find the square roots: √(16) = 4 and √(25) = 5.
2. Multiply the square roots: 4 × 5 = 20.
3. Alternatively, use the formula: √(16 × 25) = √(400) = 20.

The result is 20, demonstrating the validity of the formula.

Example 2: Decimal Numbers

Calculate √(2.25) × √(4.00):

1. Find the square roots: √(2.25) = 1.5 and √(4.00) = 2.0.
2. Multiply the square roots: 1.5 × 2.0 = 3.0.
3. Using the formula: √(2.25 × 4.00) = √(9.00) = 3.0.

The result is 3.0, confirming the formula's accuracy.
