To solve the equation \( x^{2/3} = 64 \), follow these steps:

1. **Raise both sides to the reciprocal of the exponent \( \frac{3}{2} \)**:

\[
(x^{2/3})^{3/2} = 64^{3/2}
\]

2. **Simplifying the left side**:

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

3. **Now compute the right side**:

First, calculate \( 64^{3/2} \):

- Calculate \( 64^{1/2} = \sqrt{64} = 8 \).
- Then raise the result to the third power: \( 8^3 = 512 \).

So:

\[
x = 512
\]

Thus, the value of \( x \) is \( 512 \).

Therefore, the answer is \( 512 \).
