1. **State the problem:** Find the value of the square root of 42 divided by 7, i.e., calculate $$\frac{\sqrt{42}}{7}$$. 2. **Recall the formula:** The square root of a number $x$ is written as $\sqrt{x}$ and represents a value that, when squared, gives $x$. 3. **Calculate the square root:** First, find $\sqrt{42}$. Since 42 is not a perfect square, we leave it as $\sqrt{42}$ or approximate it as $6.4807$. 4. **Divide by 7:** Now divide $\sqrt{42}$ by 7: $$\frac{\sqrt{42}}{7}$$ Using the approximate value: $$\frac{6.4807}{7} \approx 0.9258$$ 5. **Final answer:** The exact form is $$\frac{\sqrt{42}}{7}$$ and the approximate decimal value is $0.9258$.
