Jasiah · Answer 1

8/5 is rational. It is expressed as a ratio of two integers.

√4 = 2 = 2/1. This is rational because it expressed as ratio of two integers.

√64 = 8. This is rational because it expressed as ratio of two integers.

√10 = 3.16227 ... The decimal part does not end and it is irrational because it can not be expressed as ratio of two integers.

Therefore √10 is irrational.
