The equation given is:

\[
\log_2(x + 3) = \log_2(x - 3) + \log_4(16) + 5 \log_5(3)
\]

We need to simplify and solve for \(x\).

### Step 1: Simplify the logarithmic terms
1. \(\log_4(16)\): Recall that \(16 = 4^2\), so
   \[
   \log_4(16) = 2
   \]

2. \(5 \log_5(3)\): Using the logarithmic property \(a \log_b(c) = \log_b(c^a)\), this simplifies to:
   \[
   5 \log_5(3) = \log_5(3^5) = \log_5(243)
   \]

### Step 2: Substitute these into the equation
Now the equation becomes:
\[
\log_2(x + 3) = \log_2(x - 3) + 2 + \log_5(243)
\]

### Step 3: Eliminate logarithmic terms by equating arguments
Since the equation is expressed in terms of logarithms, we'll start by isolating the logarithmic expressions with base 2.

\[
\log_2(x + 3) - \log_2(x - 3) = 2
\]

Using the property of logarithms: \(\log_b(a) - \log_b(c) = \log_b\left(\frac{a}{c}\right)\), we have:
\[
\log_2\left(\frac{x + 3}{x - 3}\right) = 2
\]

### Step 4: Convert from logarithmic form to exponential form
Using the definition of a logarithm: \(\log_b(a) = c \Rightarrow b^c = a\), convert this to exponential form:
\[
\frac{x + 3}{x - 3} = 2^2 = 4
\]

### Step 5: Solve the resulting equation
Now solve:
\[
\frac{x + 3}{x - 3} = 4
\]
Multiply both sides by \(x - 3\):
\[
x + 3 = 4(x - 3)
\]
Expand the right-hand side:
\[
x + 3 = 4x - 12
\]
Now, solve for \(x\):
\[
3 + 12 = 4x - x
\]
\[
15 = 3x
\]
\[
x = 5
\]

### Final Answer:
The solution is \(x = 5\).
