In most case you must multiply the number by itself.
When the number is irrational ( meaning it cannot be expressed as a fraction,) you may end up with a one that is rational ( can be expressed as a fraction).
For example, the 2 squared is 2x2=4
square root of 2 is irrational but square root of 2 times itself is 2.
Pi is an irrational number but PixPi is Pi2 which is still irrational.
