Understanding the Square Root of 1/25
The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, we are interested in finding the square root of the fraction 1/25.
Mathematical Calculation
To find the square root of 1/25, we use the property of square roots that states:
\[
\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}
\]
Applying this to 1/25:
\[
\sqrt{\frac{1}{25}} = \frac{\sqrt{1}}{\sqrt{25}}
\]
Since the square root of 1 is 1, and the square root of 25 is 5, we get:
\[
\sqrt{\frac{1}{25}} = \frac{1}{5}
\]
Therefore, the square root of 1/25 is 1/5 or 0.2 in decimal form.
Step-by-Step Simplification
- Rewrite the fraction under the square root: \(\sqrt{\frac{1}{25}}\)
- Express the square root of a quotient as the quotient of square roots: \(\frac{\sqrt{1}}{\sqrt{25}}\)
- Calculate the square root of the numerator and the denominator: \(\frac{1}{5}\)
- Thus, the simplified form is: \(\frac{1}{5} = 0.2\)
Properties of Square Roots
Some useful properties of square roots that apply here include:
- \(\sqrt{a^2} = a\)
- \(\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}\)
- \(\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}\)
Application and Examples
Understanding how to simplify square roots is essential in various mathematical applications, such as solving equations and simplifying expressions. Here are a few more examples of square root calculations with fractions:
Expression | Simplified Form |
---|---|
\(\sqrt{\frac{3}{15}}\) | \(\frac{\sqrt{3}}{\sqrt{15}} = \frac{\sqrt{3}}{3.872}\) |
\(\sqrt{\frac{5}{10}}\) | \(\frac{\sqrt{5}}{\sqrt{10}} = \frac{\sqrt{5}}{3.162}\) |
\(\sqrt{\frac{3}{25}}\) | \(\frac{\sqrt{3}}{\sqrt{25}} = \frac{\sqrt{3}}{5} = 0.6\) |
By understanding these principles, one can tackle a wide range of mathematical problems involving square roots of fractions.
