This can be expressed as √(5/6), and it involves simplifying the expression to its simplest form by rationalizing the denominator and performing basic arithmetic operations. The steps to achieve this are straightforward and essential for understanding fractional square roots in general mathematics.

1. Rewrite the square root of the fraction as the division of square roots: \[ \sqrt{\frac{5}{6}} = \frac{\sqrt{5}}{\sqrt{6}} \]
2. Rationalize the denominator by multiplying both the numerator and the denominator by \(\sqrt{6}\): \[ \frac{\sqrt{5}}{\sqrt{6}} \times \frac{\sqrt{6}}{\sqrt{6}} = \frac{\sqrt{30}}{6} \]
3. Simplify the expression: \[ \frac{\sqrt{30}}{6} \]

This final form, \(\frac{\sqrt{30}}{6}\), is the simplified expression for the square root of 5/6. Understanding this process is crucial for students and professionals dealing with fractions and square roots in various fields of science and engineering.

The square root of a number is a value that, when multiplied by itself, gives the original number. It is denoted using the radical sign √. For example, the square root of 16 is 4, because 4 × 4 = 16. This section will help you understand the concept of square roots, including how to simplify them, and how to deal with square roots of fractions.

Definition and Basic Properties

Every nonnegative real number \( a \) has a unique nonnegative square root, called the principal square root, which is denoted by \( \sqrt{a} \). For example:

• \(\sqrt{9} = 3\) because \(3 \times 3 = 9\)
• \(\sqrt{16} = 4\) because \(4 \times 4 = 16\)

Square Root of Fractions

The square root of a fraction is calculated by taking the square root of the numerator and the denominator separately. For instance:

• \(\sqrt{\frac{4}{9}} = \frac{\sqrt{4}}{\sqrt{9}} = \frac{2}{3}\)
• \(\sqrt{\frac{5}{6}}\) can be expressed as \(\frac{\sqrt{5}}{\sqrt{6}}\).

To simplify a fraction under a square root, we can use the property:

• \(\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}\)

Simplifying Square Roots

To simplify a square root, we make the number inside the square root as small as possible. Here are some examples:

• \(\sqrt{12}\) can be simplified to \(2\sqrt{3}\).
• \(\sqrt{18}\) simplifies to \(3\sqrt{2}\).

For fractions, the process is similar. Consider the square root of \(\frac{5}{6}\). It can be left in the form \(\frac{\sqrt{5}}{\sqrt{6}}\) or rationalized to \(\frac{\sqrt{30}}{6}\) for easier handling in calculations.

Rationalizing the Denominator

Sometimes, it is useful to remove the square root from the denominator of a fraction. This process is called rationalizing the denominator. For example:

• To rationalize \(\frac{\sqrt{5}}{\sqrt{6}}\), multiply the numerator and the denominator by \(\sqrt{6}\) to get \(\frac{\sqrt{30}}{6}\).

Conclusion

Understanding square roots and their properties is essential in mathematics. Whether simplifying square roots or working with fractions, these principles will help you handle various mathematical problems with ease.
