## Proof Exercise #1 Continuation 2

Yes.

Once we have established that if 2 divides the square of an integer, it also divides the integer, what, do you think,

is our next step, from the choices below?

choice #1: Assume that the square root of 2 is a rune, with the intention of later obtaining a contradiction,

thereby proving that it must be an irrat.

choice #2: Assume what we're trying to prove, and then apply DeMorgan's Law to finalize the proof.

choice #3: Prepare to use a Pythagorean triple and a certain set of extraneous roots of a certain equation.

choice #4: Consider the power set of all runes.

choice #5: Take the squares of all the primes.
