Let's simplify the expression step-by-step. The expression given is:

\[
(8^2 + 36) \div 2 + 15
\]

### Step 1: Follow the order of operations (PEMDAS):
1. **Parentheses**: Simplify inside the parentheses first.
2. **Exponents**: Handle any exponents within the parentheses.
3. **Multiplication/Division**: From left to right.
4. **Addition/Subtraction**: From left to right.

### Step 2: Simplify the exponent inside the parentheses:
\[
8^2 = 64
\]
So the expression becomes:
\[
(64 + 36) \div 2 + 15
\]

### Step 3: Simplify inside the parentheses:
\[
64 + 36 = 100
\]
Now, the expression is:
\[
100 \div 2 + 15
\]

### Step 4: Division comes next:
\[
100 \div 2 = 50
\]
So now the expression is:
\[
50 + 15
\]

### Step 5: Finally, perform the addition:
\[
50 + 15 = 65
\]

So, the simplified value of the expression is **65**.
