Answer 1

To approximate the value of √19 on a number line, we can start by finding the nearest whole numbers to 19, which are 4 and 5. We can then estimate the distance between these two whole numbers and divide it into equal parts.

Since 19 is closer to 5 than to 4, we can estimate that the value of √19 is closer to 4.5.

Therefore, the approximate value of 19−−√ is 4.5.

The correct response is:

4.5
