Between 18.9 and 19.1

Between 6.1 and 6.2

Answer 1

To find where \(\sqrt{38}\) lies on a number line, we can first estimate its value.

We know that:
- \(6^2 = 36\)
- \(7^2 = 49\)

Since \(36 < 38 < 49\), we know that:
\[
6 < \sqrt{38} < 7
\]

Next, we can refine our estimate by squaring numbers between 6 and 7 to find a closer approximation:

- \(6.1^2 = 37.21\)
- \(6.2^2 = 38.44\)

Since \(37.21 < 38 < 38.44\), it follows that:
\[
6.1 < \sqrt{38} < 6.2
\]

Thus, \(\sqrt{38}\) lies between 6.1 and 6.2.

So the correct response is:
**Between 6.1 and 6.2.**
