Between which pair of rational numbers on a number line does 18−−√ lie?(1 point) Responses
Between 4.3 and 4.5
Between 4.2 and 4.3
Between 8.9 and 9.1
Between 9 and 9.2
To determine the rational numbers between which 18−−√ lies, we can estimate the square root of 18.
Since 16 is a perfect square, and 18 is between 16 and 25, we can estimate that the square root of 18 is between the square roots of 16 (which is 4) and 25 (which is 5).
Therefore, 18−−√ lies between the rational numbers 4 and 5 on the number line.
