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.
Rational; 62 = 36. Any rational number that is squared is still rational.
14 squared = 196, so you're looking for the sqrt of double that, ie 392, which is almost exactly 19.8
irrational
Any number, squared, is the number multiplied by itself. So 142 = 14*14. And that, is 196.
The square root of 14 is irrational. Three squared is 9, and four squared is 16; so square root of 14 is in-between 3 and 4.
12 squared is not irrational. It's 144 .
20 squared is not an irrational number. 202 = 400.
No
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.
No, it is rational.
Any number that can't be expressed as a fraction is an irrational number.
Not irrational, 12 squared equals 144.
No because pi still remains as an irrational when squared.
20 squared is 400 which is a rational number
No because 102 squared is 10404 which is a rational number
