yes, 82 is rational. Rational numbers are numbers that can be written as a fraction. Irrational Numbers cannot be expressed as a fraction.
No.
82 is an integer and not a fraction. It therefore makes little, if any, sense to write it as a mixed number. However, if you must, it can be expressed in rational form as 82/1.
No, it is rational.
It is rational. It is rational. It is rational. It is rational.

Actually, as a non-integer square root of a number, 82 is an irrational number. It has no end.
82 is an integer and not a fraction. It therefore makes little, if any, sense to write it as a mixed number. However, if you must, it can be expressed in rational form as 82/1.
Yes. Any terminating decimal is a rational number. Any repeating decimal also.

Sure. Let's take an example with numbers instead of variables. 8/9 is a rational number - the ratio of two integers. If you square it, you get (8/9)2 = 82/92 = 64/81; that is, if you square each integer, you get an integer again. Therefore, the resulting number is rational again - a number that can be expressed as the ratio of two integers. Replace with any other integers; you will still have a ratio of integers if you square it.
8.2 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its rational equivalent is 82/10 which can be simplified, if required.

1.14 is rational.
