The problem asks to simplify the following logarithmic expression:

\[
\ln\left( \frac{1}{e^{-2}} \right) + 4\ln(e^3) + \ln(e^{-2})
\]

Let's break this down step by step:

### Step 1: Simplify \(\ln\left( \frac{1}{e^{-2}} \right)\)
\[
\ln\left( \frac{1}{e^{-2}} \right) = \ln\left(e^{2}\right)
\]
Since \(\ln(e^a) = a\), we get:
\[
\ln(e^2) = 2
\]

### Step 2: Simplify \(4\ln(e^3)\)
Using the property \(\ln(e^a) = a\), we have:
\[
4\ln(e^3) = 4 \times 3 = 12
\]

### Step 3: Simplify \(\ln(e^{-2})\)
Again using the property \(\ln(e^a) = a\), we get:
\[
\ln(e^{-2}) = -2
\]

### Step 4: Combine the results
Now, adding all the simplified terms:
\[
2 + 12 + (-2) = 12
\]

### Final Answer:
The simplified form of the given expression is:
\[
12
\]
