\sqrt{16} - 4 \sqrt{5} \cdot 7 \cdot 10^6


The given expression is:

\[
\sqrt{16} - 4 \sqrt{5} \cdot 7 \cdot 10^6
\]

### Step 1: Simplify \(\sqrt{16}\)
We know that:
\[
\sqrt{16} = 4
\]

### Step 2: Multiply the remaining terms
Now, simplify the remaining part of the expression:
\[
4 \sqrt{5} \cdot 7 \cdot 10^6 = (4 \cdot 7 \cdot 10^6) \cdot \sqrt{5}
\]
First, calculate the constants:
\[
4 \cdot 7 = 28
\]
Thus:
\[
28 \cdot 10^6 = 28 \times 10^6
\]
The expression becomes:
\[
28 \cdot 10^6 \cdot \sqrt{5}
\]

### Step 3: Combine the terms
Now the full expression is:
\[
4 - 28 \cdot 10^6 \cdot \sqrt{5}
\]

This is the simplified form of the given expression.
