Contradiction Problem 1


Start by writing out the negation of the claim, so you know what your starting information is.

Remember that a rational number is defined as a number which can be represented as a ratio \(\frac{c}{d}\) of two integers c and d, where d is not equal to zero.

Keep an open mind about what the contradiction will be. Try simplifying the starting equation and see if you can produce an equation that is obviously unreasonable.
