Find the 4th term from the end in the expansion of `(x^(3)/ 2 - 2 /x^(2))^(9).`

Explanation

To find the 4th term from the end in the expansion of \((\frac{x^3}{2} - \frac{2}{x^2})^9\), we can follow these steps:

### Step 1: Identify the general term in the binomial expansion
The general term \(T_{r+1}\) in the expansion of \((a + b)^n\) is given by:
\[ T_{r+1} = \binom{n}{r} a^{n-r} b^r \]
In our case, \(a = \frac{x^3}{2}\), \(b = -\frac{2}{x^2}\), and \(n = 9\).
