Between which pair of rational numbers on a number line does 18−−√18 lie?(1 point)
1 answer
To determine between which pair of rational numbers $\sqrt{18}$ lies, we first estimate its value. Since $4^2=16$ and $5^2=25$, we know that $\sqrt{18}$ is between 4 and 5. Therefore, $\sqrt{18}$ lies between the rational numbers $\boxed{4}$ and $\boxed{5}$.
