1. 2-root 5 = root 5= 2.23606
Substitute 5 in 2- root 5 = 2-2.23606 = 0.23606 which is non recurring and non terminating so it’s irrational
2. (3+root23)-root23
+root 23 and minus root 23 gets canceled and remaining will be 3 or can be written as 3/1 so it’s a rational number
3.2root7/2root7

4.1/root 2 answer is simple a rational number is in the form of p/q where q is not equal to zero and also the denominator should not be a root (but once check the photos) for clear explanation
5. 2pi = pi = 3.1415
2x3.1415= 6.2830 which is non recurring and non terminating hope this helps. Try to mark as brainlist
