Understanding the Problem

The problem asks us to find an equivalent equation to the given logarithmic equation $\log _x 36 = 2$ . To solve this problem, we need to understand the properties of logarithms and how to convert them into exponential form.

Logarithmic Properties

A logarithm is the inverse operation of exponentiation. In other words, if $y = \log _x a$ , then $x^y = a$ . This property is the foundation of logarithmic equations and is essential to solving this problem.

Converting Logarithmic to Exponential Form

To convert the given logarithmic equation $\log _x 36 = 2$ into exponential form, we need to apply the property mentioned above. This means that if $y = \log _x a$ , then $x^y = a$ . In this case, $a = 36$ and $y = 2$ . Therefore, we can rewrite the equation as $x^2 = 36$ .

Analyzing the Options

Now that we have converted the logarithmic equation into exponential form, we can analyze the given options to find the equivalent equation.

Option A: $2^x = 36$

This option is not equivalent to the given logarithmic equation. The base of the exponential function is 2, whereas the base of the logarithmic function is x. Therefore, this option is not correct.

Option B: $x^2 - 36$

This option is not equivalent to the given logarithmic equation. The equation $x^2 - 36$ is a quadratic equation, whereas the given logarithmic equation is an exponential equation. Therefore, this option is not correct.

Option C: $36^x = 2$

This option is not equivalent to the given logarithmic equation. The base of the exponential function is 36, whereas the base of the logarithmic function is x. Therefore, this option is not correct.

Option D: $x^2 = 36^2$

This option is equivalent to the given logarithmic equation. We can rewrite the equation $x^2 = 36^2$ as $x^2 = 1296$ , which is equivalent to the equation $x^2 = 36$ that we obtained by converting the logarithmic equation into exponential form.

Conclusion

In conclusion, the equivalent equation to $\log _x 36 = 2$ is $x^2 = 36^2$ . This equation is obtained by converting the logarithmic equation into exponential form using the properties of logarithms.

Final Answer

The final answer is: $\boxed{D}$
