Understanding the Square Root of 8
The square root of 8 is an important mathematical concept that appears in various calculations. To understand it better, let's break it down step by step.
Basic Definition:
The square root of a number \( x \) is a value that, when multiplied by itself, gives the number \( x \). Mathematically, if \( y \) is the square root of \( x \), then:
\[
y = \sqrt{x} \quad \text{and} \quad y^2 = x
\]
For \( x = 8 \), we have:
\[
y = \sqrt{8}
\]
Simplifying the Square Root of 8:
To simplify \( \sqrt{8} \), we can express 8 as a product of its prime factors:
\[
8 = 2 \times 2 \times 2 = 2^3
\]
Taking the square root of both sides, we get:
\[
\sqrt{8} = \sqrt{2^3} = \sqrt{2^2 \times 2} = 2 \sqrt{2}
\]
Thus, the simplified form of the square root of 8 is:
\[
\sqrt{8} = 2 \sqrt{2}
\]
Approximate Value:
Using a calculator, we can find the approximate decimal value of \( \sqrt{8} \):
\[
\sqrt{8} \approx 2.828
\]
This value is often rounded to three decimal places for simplicity.
Table Summary:
| Expression | Value |
| \( \sqrt{8} \) | 2.828 (approx.) |
| \( 2 \sqrt{2} \) | 2.828 (approx.) |
By understanding the square root of 8, you can better grasp its role in various mathematical calculations and applications.
Calculation of 3 times Square Root of 8
Calculating 3 times the square root of 8 is a straightforward process. Follow the detailed steps below to understand how this is done.
- Understand the Square Root of 8:
- Multiply by 3:
- Distribute the Multiplication:
- Approximate the Final Value:
From our previous section, we know that:
\[
\sqrt{8} = 2 \sqrt{2} \approx 2.828
\]
Next, we multiply the square root of 8 by 3. Using the simplified form:
\[
3 \times \sqrt{8} = 3 \times 2 \sqrt{2}
\]
We can distribute the multiplication as follows:
\[
3 \times 2 \sqrt{2} = (3 \times 2) \sqrt{2} = 6 \sqrt{2}
\]
To find the approximate decimal value, we use:
\[
6 \sqrt{2} \approx 6 \times 1.414 = 8.484
\]
So, 3 times the square root of 8 is approximately 8.484.
Summary in a Table:
| Step | Calculation | Result |
| Square Root of 8 | \(\sqrt{8}\) | \(2 \sqrt{2} \approx 2.828\) |
| Multiply by 3 | \(3 \times \sqrt{8}\) | \(6 \sqrt{2}\) |
| Approximate Value | \(6 \sqrt{2}\) | \(\approx 8.484\) |
By following these steps, you can accurately calculate 3 times the square root of 8, both in exact and approximate forms.
