Introduction

Solving equations involving square roots can be a challenging task, especially when the equation involves multiple square roots. In this problem, we are given the equation $\sqrt{36x-9} = 3\sqrt{4x-2}$, and we need to find the value of $x$ that satisfies this equation. We will use algebraic manipulations and properties of square roots to solve this equation.

Step 1: Square both sides of the equation

To eliminate the square roots, we can square both sides of the equation. This will give us an equation without any square roots.

$$\left(\sqrt{36x-9}\right)^2 = \left(3\sqrt{4x-2}\right)^2$$

Using the property of exponents that $(a^m)^n = a^{mn}$, we can simplify the equation as follows:

$$36x-9 = 9(4x-2)$$

Step 2: Expand and simplify the equation

Now, we can expand and simplify the equation by multiplying the terms inside the parentheses.

$$36x-9 = 36x-18$$

Step 3: Solve for x

Now, we can solve for $x$ by isolating the variable on one side of the equation.

$$-9 = -18$$

This equation is not true for any value of $x$. Therefore, we need to go back to the previous step and try a different approach.

Step 4: Go back to the previous step and try a different approach

Let's go back to the previous step and try a different approach. Instead of squaring both sides of the equation, we can try to isolate the square root term on one side of the equation.

$$\sqrt{36x-9} = 3\sqrt{4x-2}$$

We can square both sides of the equation, but this time, we will square the left-hand side of the equation.

$$\left(\sqrt{36x-9}\right)^2 = \left(3\sqrt{4x-2}\right)^2$$

Using the property of exponents that $(a^m)^n = a^{mn}$, we can simplify the equation as follows:

$$36x-9 = 9(4x-2)$$

This is the same equation we got in the previous step. However, this time, we can try to solve for $x$ by isolating the variable on one side of the equation.

$$36x-9 = 36x-18$$

Subtracting $36x$ from both sides of the equation, we get:

$$-9 = -18$$

This equation is not true for any value of $x$. Therefore, we need to try a different approach.
