To find the product \( 85 - \sqrt{3} \cdot \sqrt{32} \), we first need to simplify the expression involving the square roots.
The term \( \sqrt{32} \) can be simplified: \[ \sqrt{32} = \sqrt{16 \cdot 2} = \sqrt{16} \cdot \sqrt{2} = 4\sqrt{2} \]
Now, we substitute this back into our expression: \[ 85 - \sqrt{3} \cdot \sqrt{32} = 85 - \sqrt{3} \cdot 4\sqrt{2} = 85 - 4\sqrt{6} \]
Therefore, the expression \( 85 - \sqrt{3} \cdot \sqrt{32} \) in simplest radical form is: \[ \boxed{85 - 4\sqrt{6}} \]
