5 squared is 5*5 is 25. 25 is not an irrational number.
No because 25 is a rational number
4/25 squared is 16/625 = 0.0256 . That's a perfectly rational number.
Sometimes. eg the irrational number √2 squared is 2 which is rational (2 = 2/1) eg the irrational number √(√2) squared is √2 which is irrational.
Because it has no number that can be squared to make it.
