When dealing with square roots, it's important to recognize that every positive number has two square roots: one positive and one negative. For example, the square root of 16 is 4 and -4 because both 4² and (-4)² equal 16.

Similarly, the fraction \(\frac{16}{36}\) has two square roots, which can be expressed as follows:

• Positive square root: \(\sqrt{\frac{16}{36}} = \frac{\sqrt{16}}{\sqrt{36}} = \frac{4}{6} = \frac{2}{3}\)
• Negative square root: \(-\sqrt{\frac{16}{36}} = -\frac{\sqrt{16}}{\sqrt{36}} = -\frac{4}{6} = -\frac{2}{3}\)

Therefore, the negative square root of \(\frac{16}{36}\) is \(-\frac{2}{3}\).

To generalize, the negative square root of a fraction \(\frac{a}{b}\) where \(a\) and \(b\) are both perfect squares can be found using the formula:

\[
-\sqrt{\frac{a}{b}} = -\frac{\sqrt{a}}{\sqrt{b}}
\]

For example:

• Negative square root of \(\frac{25}{49}\): \(-\sqrt{\frac{25}{49}} = -\frac{\sqrt{25}}{\sqrt{49}} = -\frac{5}{7}\)
• Negative square root of \(\frac{9}{16}\): \(-\sqrt{\frac{9}{16}} = -\frac{\sqrt{9}}{\sqrt{16}} = -\frac{3}{4}\)

In more complex cases where \(a\) and \(b\) are not perfect squares, the same principles apply, but the results might not simplify as neatly. The use of negative square roots is common in various mathematical applications, including solving quadratic equations and representing complex numbers.

Always remember to consider both the positive and negative roots when solving equations involving square roots to ensure all possible solutions are found.
