guapka [62]

Answer:

√37

Step-by-step explanation:

An irrational number is a number that never terminates nor repeats.

Let's go through each of the answer choices.

1) √100 is just 10. This is not irrational.

2) √81 is just 9. This is again not irrational.

3) √64 is 8. Not irrational.

4) √49 is 7. Again, not irrational.

5) √37 is 6.08276253... This number will never end and it doesn't repeat. Therefore, √37 is irrational.

And this is our answer.

And we're done!
