The equation shown in the image is:

\[
\left( 3 \sqrt[3]{\frac{2}{3}} \right)^{2y - 3} = \frac{27}{8}
\]

Let me walk you through the steps to solve this equation:

### Step 1: Simplify the expression inside the parentheses

First, break down the expression \( 3 \sqrt[3]{\frac{2}{3}} \).

This can be rewritten as:

\[
3 \cdot \left( \frac{2}{3} \right)^{1/3}
\]

Which simplifies to:

\[
3 \cdot \frac{2^{1/3}}{3^{1/3}} = 3^{1 - 1/3} \cdot 2^{1/3} = 3^{2/3} \cdot 2^{1/3}
\]

### Step 2: Solve the equation

Now the original equation becomes:

\[
\left( 3^{2/3} \cdot 2^{1/3} \right)^{2y - 3} = \frac{27}{8}
\]

Using the property of exponents, we can distribute the exponent \( 2y - 3 \):

\[
3^{(2/3)(2y - 3)} \cdot 2^{(1/3)(2y - 3)} = \frac{27}{8}
\]

### Step 3: Express \( \frac{27}{8} \) as powers of 3 and 2

Note that:

\[
\frac{27}{8} = \frac{3^3}{2^3}
\]

Now, the equation becomes:

\[
3^{(2/3)(2y - 3)} \cdot 2^{(1/3)(2y - 3)} = 3^3 \cdot 2^{-3}
\]

### Step 4: Set the exponents equal

For the equation to be true, the exponents of 3 and 2 on both sides must be equal.

For the powers of 3:

\[
\frac{2}{3}(2y - 3) = 3
\]

Solving this:

\[
2(2y - 3) = 9
\]

\[
4y - 6 = 9
\]

\[
4y = 15 \implies y = \frac{15}{4}
\]

For the powers of 2:

\[
\frac{1}{3}(2y - 3) = -3
\]

Solving this:

\[
2y - 3 = -9
\]

\[
2y = -6 \implies y = -3
\]

There seems to be a contradiction in the solutions obtained from the powers of 3 and 2. I'll check the steps and approach again to clarify.
