1. Let's start by understanding the problem: You want to find the square root of 5.8. 2. The square root of a number $x$ is a value $y$ such that $y^2 = x$. 3. To approximate $\sqrt{5.8}$, we can use a calculator or estimate between perfect squares. Since $2^2 = 4$ and $3^2 = 9$, $\sqrt{5.8}$ is between 2 and 3. 4. Using a calculator, $\sqrt{5.8} \approx 2.4083$. 5. Therefore, the approximate value of $\sqrt{5.8}$ is $2.4083$. This completes the solution for the first question you asked.
