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.
5 squared is 5*5 is 25. 25 is not an irrational number.
Because it has no number that can be squared to make it.
20 squared is 400 which is a rational number
No because 102 squared is 10404 which is a rational number
20 squared is not an irrational number. 202 = 400.
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.
5 squared is 5*5 is 25. 25 is not an irrational number.
Any number that can't be expressed as a fraction is an irrational number.
No because 7 squared equals 49 which is a rational number but the square root of 7 is an irrational number
22=4, so no, it's not an irrational number.
Because it has no number that can be squared to make it.
20 squared is 400 which is a rational number
No because 102 squared is 10404 which is a rational number
Rational.
Rational.
No. Perfect squares as the squares of the integers, whereas irrational squares as the squares of irrational numbers, but some irrational numbers squared are whole numbers, eg √2 (an irrational number) squared is a whole number.
