To multiply the square roots \( \sqrt{11} \) and \( \sqrt{67} \), you can use the property of square roots that states \( \sqrt{a} \cdot \sqrt{b} = \sqrt{a \cdot b} \).
So, \[ \sqrt{11} \cdot \sqrt{67} = \sqrt{11 \cdot 67}. \]
Now, calculate \( 11 \cdot 67 \): \[ 11 \cdot 67 = 737. \]
Thus, \[ \sqrt{11} \cdot \sqrt{67} = \sqrt{737}. \]
Therefore, the exact answer is: \[ \sqrt{737}. \]
