Question

If you follow the steps necessary to prove that square root 7 is irrational (use a proof by contradiction) to prove that square root 4 is irrational, where would you fail? You may not answer : I know that it isn't or something similar.

Answer 1

Sorry, i wish i could help, but really the only thing i know is that 4 is 2 by 2 so using another equation to try to prove otherwise is irrational in itself
