1. The problem is to find the root of 67. 2. Usually, "root" refers to the square root, which means finding a number $x$ such that $$x^2 = 67$$. 3. The formula for the square root is $$x = \sqrt{67}$$. 4. Since 67 is not a perfect square, we approximate the square root using a calculator or estimation. 5. The approximate value is $$\sqrt{67} \approx 8.185$$. 6. Therefore, the root of 67 is approximately 8.185.
