Understanding the Problem

When dealing with radical expressions, it's essential to simplify them to their most basic form. This involves breaking down the radicals into their prime factors and then simplifying the resulting expression. In this article, we'll explore how to simplify the quotient $\frac{\sqrt{36}}{\sqrt{4}}$ and determine which of the given choices is equivalent to this expression.

Simplifying the Quotient

To simplify the quotient $\frac{\sqrt{36}}{\sqrt{4}}$ , we need to start by simplifying the square roots individually. The square root of 36 can be simplified as follows:

$\sqrt{36} = \sqrt{6^2} = 6$

Similarly, the square root of 4 can be simplified as follows:

$\sqrt{4} = \sqrt{2^2} = 2$

Now that we have simplified the square roots, we can substitute these values back into the original quotient:

$\frac{\sqrt{36}}{\sqrt{4}} = \frac{6}{2}$

Simplifying the Fraction

The fraction $\frac{6}{2}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This gives us:

$\frac{6}{2} = \frac{3}{1} = 3$

Therefore, the simplified form of the quotient $\frac{\sqrt{36}}{\sqrt{4}}$ is 3.

Evaluating the Choices

Now that we have simplified the quotient, let's evaluate the given choices to determine which one is equivalent to the simplified expression.

A. $\frac{\sqrt{2}}{2}$ : This choice is not equivalent to the simplified expression 3.
B. $\sqrt{12}$ : This choice is not equivalent to the simplified expression 3.
C. 3: This choice is equivalent to the simplified expression 3.
D. 9: This choice is not equivalent to the simplified expression 3.

Conclusion

In conclusion, the simplified form of the quotient $\frac{\sqrt{36}}{\sqrt{4}}$ is 3. This is the correct answer among the given choices. When dealing with radical expressions, it's essential to simplify them to their most basic form to ensure accuracy and clarity.
