Which irrational number is between √14 and √18

√10
√13
√19
√15

√15

To determine which irrational number is between √14 and √18, we can calculate the approximate values of the given square roots.

√14 ≈ 3.74
√18 ≈ 4.24

Now, we need to find the irrational number between these values. Let's calculate the approximate values of the remaining options:

√10 ≈ 3.16
√13 ≈ 3.61
√19 ≈ 4.36
√15 ≈ 3.87

From these values, we can see that √13 is between √14 and √18. Therefore, the irrational number between √14 and √18 is √13.
